Hano hari amakuru yamakuru yinganda za Baiyear.Ibikurikira, Baiyear izagabanya uburyo bwo guterwa inshinge mu ngingo nyinshi kugirango tumenye isesengura ryibikoresho fatizo byo guterwa inshinge, kuko hari byinshi birimo.Ibikurikira ni ingingo ya gatatu.
(5).BS (K ibikoresho)
1. Imikorere ya BS
BS ni butadiene-styrene copolymer, ifite ubukana nubworoherane, ubukana buke (bworoshye) no gukorera mu mucyo.Uburemere bwihariye bwibikoresho bya BS ni 1.01f \ cm3 (bisa namazi).Ibikoresho biroroshye kurangi, bifite amazi meza, kandi byoroshye gukora no gutunganya.
2.Ibikorwa biranga BS
Ubushyuhe bwo gutunganya ibipimo bya BS muri rusange ni 190-225 ° C, kandi ubushyuhe bwububiko ni byiza 30-50 ° C.Ibikoresho bigomba kuba byumye mbere yo kubitunganya, kubera ubwiza bwabyo bwiza, umuvuduko wo gutera inshinge n'umuvuduko wo gutera inshinge.
(6).PMMA (Acrylic)
1. Imikorere ya PMMA
PMMA ni polymer amorphous, ikunze kwitwa plexiglass.Gukorera mu mucyo bihebuje, kurwanya ubushyuhe bwiza (ubushyuhe bwo guhindura ubushyuhe bwa 98 ° C), no kurwanya ingaruka nziza.Ibicuruzwa byayo bifite imbaraga ziciriritse ziciriritse, ubukana buke bwo hejuru, kandi byoroshye gushushanya nibintu bikomeye hanyuma bigasiga ibimenyetso, bisa na PS.Ntibyoroshye kuvunika no gucika, kandi uburemere bwihariye ni 1.18g / cm3.
PMMA ifite ibyiza byiza bya optique hamwe nuburyo bwo guhangana nikirere.Kwinjira k'umucyo wera ni hejuru ya 92%.Ibicuruzwa bya PMMA bifite birefringence nkeya kandi birakwiriye cyane cyane gukora disiki ya videwo.PMMA ifite ibyumba byubushyuhe bwo hejuru.Gucika intege birashobora kubaho hamwe no kongera umutwaro nigihe.
2. Ibikorwa biranga PMMA
Ibisabwa gutunganya PMMA birakomeye, kandi birumva cyane ubushuhe nubushuhe.Igomba gukama neza mbere yo gutunganywa (bisabwa ko byuma ni 90 ° C, amasaha 2 ~ 4).° C) no kubumba munsi yigitutu, ubushyuhe bwububiko nibyiza 65-80 ° C.
Guhagarara kwa PMMA ntabwo ari byiza cyane, kandi bizangirika nubushyuhe bwinshi cyangwa igihe kirekire cyo gutura ku bushyuhe bwo hejuru.Umuvuduko wa screw ntugomba kuba munini cyane (hafi 60%), kandi ibice binini bya PMMA bikunda “ubusa”, bigomba gutunganywa hakoreshejwe irembo rinini, “ubushyuhe buke bwibintu, ubushyuhe bukabije, umuvuduko mwinshi” buryo.
3.Uburyo busanzwe bwo gusaba: inganda zitwara ibinyabiziga (ibikoresho byerekana ibimenyetso, imbaho zikoreshwa, nibindi), inganda zimiti (ibikoresho byo kubika amaraso, nibindi), gukoresha inganda (disiki ya videwo, diffuseri yumucyo), ibicuruzwa byabaguzi (ibikombe byokunywa, ububiko, nibindi. ).
(7) PE (polyethylene)
1. Imikorere ya PE
PE ni plastiki ifite umusaruro mwinshi muri plastiki.Irangwa nubwiza bworoshye, butari uburozi, igiciro gito, gutunganya neza, kurwanya imiti myiza, ntibyoroshye kubora, kandi bigoye gucapa.PE ni polymer isanzwe.
Ifite ubwoko bwinshi, bukunze gukoreshwa ni LDPE (polyethylene yubucucike buke) na HDPE (polyethylene yuzuye cyane), ni plastiki yoroheje ifite imbaraga nke hamwe nuburemere bwihariye bwa 0,94g / cm3 (ntoya kuruta amazi);ubucucike buke cyane LLDPE isubirana (Ubucucike buri munsi ya 0.910g / cc, n'ubucucike bwa LLDPE na LDPE buri hagati ya 0.91-0.925).
LDPE yoroshye, (bakunze kwita reberi yoroshye) HDPE izwi cyane nka rubber yoroshye.Birakomeye kuruta LDPE kandi ni igice cya kirisiti.Guhagarika ibidukikije bibaho.Guhangayikishwa imbere birashobora kugabanuka ukoresheje ibikoresho bifite imiterere mike cyane, bityo bikagabanya gucika.Biroroshye gushonga mumashanyarazi ya hydrocarubone mugihe ubushyuhe buri hejuru ya 60 ° C, ariko kurwanya kwayo gusesa nibyiza kurenza LDPE.
Ubukonje bwinshi bwa HDPE butera ubwinshi bwayo, imbaraga zingana, ubushyuhe bwo kugoreka ubushyuhe bwinshi, ubukonje hamwe n’imiti ihamye.Kurwanya kwinjira cyane kuruta LDPE.PE-HD ifite imbaraga nke zingaruka.Ibyiza bigenzurwa cyane nubucucike no gukwirakwiza uburemere bwa molekile.
HDPE ikwiranye no guterwa inshinge ifite kugabanya uburemere bwa molekile.Kubucucike bwa 0,91 ~ 0.925g / cm3, tuyita ubwoko bwa mbere bwa PE-HD;kubera ubucucike bwa 0,926 ~ 0,94g / cm3, byitwa ubwoko bwa kabiri bwa HDPE;kubwinshi bwa 0,94 ~ 0.965g / cm3, byitwa ubwoko bwa kabiri bwa HDPE Nubwoko bwa gatatu HDPE.
Ibiranga imigendekere yibi bikoresho nibyiza cyane, hamwe na MFR hagati ya 0.1 na 28. Iyo uburemere bwa molekile burenze, niko ibintu bitagenda neza biranga LDPE, ariko nimbaraga zingaruka.HDPE ikunda guhangayikishwa n'ibidukikije.Kumeneka birashobora kugabanuka ukoresheje ibikoresho bifite ibintu bike bitemba kugirango ugabanye imihangayiko y'imbere.HDPE ishonga byoroshye mumashanyarazi ya hydrocarubone mugihe ubushyuhe buri hejuru ya 60C, ariko kurwanya kwangirika nibyiza kuruta ibya LDPE.
LDPE ni kimwe cya kabiri cya kirisiti hamwe no kugabanuka cyane nyuma yo kubumba, hagati ya 1.5% na 4%.
LLDPE (Linear Low Density Polyethylene) ifite uburakari bukabije, kwinjira, ingaruka no kurwanya amarira bituma LLDPE ibera firime.Kurwanya kwiza kwangiza ibidukikije, kurwanya ubushyuhe buke no guhangana nintambara bituma LLDPE ishimisha imiyoboro, gusohora impapuro hamwe nibisabwa byose.Porogaramu iheruka ya LLDPE ni nk'igiti cyo kumena imyanda no gutondekanya ibyuzi.
2. Ibikorwa biranga PE
Ikintu kigaragara cyane mu bice bya PE ni uko igipimo cyo kugabanuka ari kinini, gikunda kugabanuka no guhindura ibintu.PE ibikoresho bifite amazi make, ntabwo rero bigomba gukama.PE ifite ubushyuhe bwagutse bwo gutunganya kandi ntabwo byoroshye kubora (ubushyuhe bwo kubora ni 320 ° C).Niba igitutu ari kinini, ubucucike bwigice buzaba bwinshi kandi igipimo cyo kugabanuka kizaba gito.
Amazi ya PE aringaniye, uburyo bwo gutunganya bugomba kugenzurwa cyane, kandi ubushyuhe bwibumba bugomba guhora (40-60 ℃).Urwego rwo korohereza PE rufitanye isano nuburyo bwo kubumba.Ifite ubushyuhe bwo hejuru bukonje nubushyuhe bwo hasi, kandi kristu iri hasi.Mugihe cyo gutegera, bitewe na anisotropy yo kugabanuka, imihangayiko yimbere iba yibanze, kandi ibice bya PE bikunda guhinduka no gucika.
Ibicuruzwa bishyirwa mubwogero bwamazi mumazi ashyushye kuri 80 ° C, bishobora kugabanya umuvuduko kurwego runaka.Mugihe cyo kubumba, ubushyuhe bwibintu nubushyuhe bwububiko bigomba kuba hejuru, kandi igitutu cyo gutera inshinge kigomba kuba munsi hashingiwe ku kwemeza ubuziranenge bwibice.Gukonjesha kubumba birasabwa cyane cyane kwihuta kandi kimwe, kandi ibicuruzwa bizaba bishyushye mugihe bimanutse.
Kuma HDPE: gukama ntibisabwa niba bibitswe neza.Gushonga ubushyuhe 220 ~ 260C.Kubikoresho bifite molekile nini, icyifuzo cyo gushonga ubushyuhe buri hagati ya 200 na 250C.
Ubushyuhe bukabije: 50 ~ 95C.Ibice bya plastiki bifite uburebure bwurukuta munsi ya 6mm bigomba gukoresha ubushyuhe bwo hejuru, naho ibice bya plastiki bifite uburebure bwurukuta hejuru ya 6mm bigomba gukoresha ubushyuhe buke.Ubushyuhe bukonje bwigice cya plastiki bugomba kuba bumwe kugirango ugabanye itandukaniro ryo kugabanuka.Mugihe cyiza cyo gutunganya neza, diameter yo gukonjesha ya diameter ntigomba kuba munsi ya 8mm kandi intera iva hejuru yububiko igomba kuba muri 1.3d (aho “d” ni diameter yumuyoboro ukonje).
Umuvuduko wo gutera inshinge: 700 ~ 1050bar.Umuvuduko wo gutera inshinge: Birashoboka ko inshinge yihuta.Abiruka n'amarembo: Diameter yiruka iri hagati ya 4 na 7.5mm, kandi uburebure bwiruka bugomba kuba bugufi bushoboka.Ubwoko butandukanye bwamarembo burashobora gukoreshwa, kandi uburebure bwirembo ntibugomba kurenga 0,75mm.Cyane cyane kibereye gukoresha imashini ishyushye.
Umutungo "woroshye-urambuye" wa LLDPE ni imbogamizi mubikorwa bya firime, kandi firime ya firime ya LLDPE ntabwo ihagaze neza nka LDPE.Ikinyuranyo cyurupfu kigomba kwagurwa kugirango wirinde kugabanuka kwinjiza bitewe numuvuduko mwinshi wumugongo no kuvunika.Ibipimo rusange bipfa kuba LDPE na LLDPE ni 0.024-0.040 muri na 0.060-0.10 muri.
3. Urutonde rusanzwe rusaba:
LLDPE yinjiye mu masoko gakondo ya polyethylene, harimo firime, kubumba, imiyoboro, insinga na kabili.Anti-leakage mulch nisoko rishya rya LLDPE.Mulch, urupapuro runini rusohoka rukoreshwa nk'imyanda hamwe n'imyanda ya pisine kugirango hirindwe imyanda cyangwa kwanduza uduce tuyikikije.
Ingero zirimo gukora imifuka, imifuka yimyanda, gupakira ibintu bya elastike, inganda zikora inganda, igitambaro cyo kumasuka hamwe nudukapu two guhaha, ibyo byose bifashisha iyi resin yongerewe imbaraga nubukomere.Filime zisobanutse, nkimifuka yimigati, yiganjemo LDPE kubera igihu cyayo cyiza.
Ariko, kuvanga LLDPE na LDPE bizamura imbaraga.Kurwanya gucengera no gukomera kwa firime ya LDPE bitabangamiye cyane firime.
Urutonde rwa porogaramu ya HDPE: ibikoresho bya firigo, ibikoresho byo kubikamo, ibikoresho byo mu gikoni byo mu rugo, ibifuniko bifunga, nibindi.
Gukomeza, niba ushaka kumenya byinshi, nyamuneka twandikire.Baiyear ni uruganda runini rugizwe ninganda zikora plastike, gutera inshinge no gutunganya ibyuma.Cyangwa urashobora gukomeza kwitondera ikigo cyamakuru cyurubuga rwacu: www.baidasy.com, tuzakomeza kuvugurura amakuru yubumenyi ajyanye ninganda zitunganya inshinge.
