Poly (vinyl chloride) Poly (vinyl chloride)

PVC ni plastiki ya polyvinyl chloride, ibara ryiza, irwanya ruswa, irakomeye kandi iramba, bitewe no kongeramo plasitike, imiti igabanya ubukana nibindi bikoresho bifasha uburozi mubikorwa byo gukora, bityo ibicuruzwa byayo ntibibika ibiryo nibiyobyabwenge.

PVC ni polyvinyl chloride, nigicuruzwa cya plastiki gikozwe mumavuta 43% numunyu wa 57%.Ugereranije nubundi bwoko bwibicuruzwa bya pulasitike, PVC ikoresha ibikoresho bibisi neza kandi igabanya gukoresha lisansi.Muri icyo gihe, gukoresha ingufu za PVC ni bike cyane.Kandi mugihe cyo gukoresha ibicuruzwa bya PVC bitinze, birashobora gukoreshwa kandi bigahinduka mubindi bicuruzwa bishya cyangwa gutwikwa kugirango ubone ingufu.

PVC mu musaruro izongeramo stabilisateur, ariko stabilisateur ifite ingingo zidafite uburozi nuburozi, gusa wongereho umunyu wambere nka stabilisateur uburozi, bizana ingaruka zihishe.Ariko ibicuruzwa bya PVC bivanze, inganda zimwe na zimwe zikoresha umunyu wa sisitemu nka stabilisateur, biragoye kubahiriza ibipimo byubuzima bijyanye.Mugihe abaguzi bahisemo ibikoresho bya PVC, nibyiza kujya mumasoko asanzwe yubaka ibikoresho bifite izina ryiza kandi ryiza, hanyuma ugasaba uwabitanze gutanga raporo yikizamini.Abaguzi bagomba kwitondera kugenzura inyandiko n'ibimenyetso bijyanye, kubona "ibijyanye n’amazi yo kunywa amazi y’ibicuruzwa ubuzima bw’ubuzima" bifite umutekano.

UPVC

Choride ya polyvinyl ikomeye (UPVC)

UPVC, izwi kandi nka PVC ikomeye, ni amorphous thermoplastic resin ikozwe muri vinyl chloride monomer na polymerisation reaction hamwe ninyongeramusaruro zimwe na zimwe (nka stabilisateur, amavuta, yuzuza, nibindi).

Usibye gukoresha inyongeramusaruro, uburyo bwo kuvanga guhindura hamwe nibindi bisigarira nabwo bwakoreshejwe, kuburyo bufite agaciro kagaragara.Ibisigarira ni CPVC, PE, ABS, EVA, MBS nibindi.

Amashanyarazi ya UPVC ni menshi kandi amazi ni mabi.Nubwo igitutu cyo gutera inshinge hamwe nubushyuhe bwashushe byiyongereye, amazi ntashobora guhinduka cyane.Byongeye kandi, ubushyuhe bwo gukora bwa resin buri hafi cyane yubushyuhe bwangirika bwumuriro, kandi ubushyuhe bwubushyuhe bwa resin bushobora kuboneka ni bugufi cyane, kubwibyo ni ubwoko bwibintu bigoye gukora.

Ibikoresho bya UPVC, ibyiza byumuyoboro

Umucyo woroshye: Umubare wibikoresho bya UPVC ni 1/10 gusa cyuma, byoroshye gutwara, gushiraho no kugabanya ibiciro.

Kurwanya imiti isumba iyindi: UPVC ifite aside irwanya cyane kandi irwanya ishingiro, usibye aside ikomeye nishingiro hafi yo kwiyuzuzamo cyangwa ibintu bikomeye bya Oxidising atmaximun.

Kutayobora: Ibikoresho bya UPVC ntibishobora kuyobora amashanyarazi, kandi ntibishobora kwangizwa na electrolysis hamwe nubu, ntabwo rero bikenewe gutunganywa kabiri.

Ntushobora gutwika, cyangwa gushyigikira gutwikwa, nta mpungenge z'umuriro.

Kwiyubaka byoroshye, igiciro gito: gukata no guhuza biroroshye cyane, gukoresha imyitozo ya PVC glue ihuza byagaragaye ko ari umutekano mwiza, imikorere yoroshye, igiciro gito.

Kuramba: Ubushyuhe buhebuje, kandi ntibushobora kwangizwa na bagiteri na fungi.

Kurwanya muke, umuvuduko mwinshi: urukuta rwimbere ruroroshye, gutakaza amazi gutemba ni nto, umwanda ntiworoshye kwizirika kurukuta rworoshye, kubungabunga biroroshye, ikiguzi cyo kubungabunga ni gito.

Polipropilen polypropilene polypropilene polypropilene

PP ni plastiki ya polypropilene, idafite uburozi, uburyohe, irashobora gushirwa mumazi 100 ℃ itetse nta guhindagurika, nta byangiritse, aside isanzwe, ibishishwa kama alkali hafi ya byose nta ngaruka bigira kuri yo.Ikoreshwa cyane mukurya ibikoresho.

Polypropilene yahinduwe na polipropilene monomer.Ibyingenzi byingenzi byari polypropilene.Ukurikije ibigize monomer yitabira polymerisation, irashobora kugabanywamo ubwoko bubiri: polymerisation homogeneous polymerisation na copolymerisation.Homopolymer polypropylene ikozwe muri polymer imwe ya monomer imwe kandi ifite kristu nyinshi, imbaraga za mashini hamwe no kurwanya ubushyuhe.Copolymerized polypropylene ikoporora mu kongeramo umubare muto wa Ethylene monomer.

Ibyingenzi byingenzi:

1. Kugaragara n'ibiranga umubiri: ibara risanzwe, ibice bya silindrike ni umweru kandi byoroshye, ibishashara;Ntabwo ari uburozi, uburyohe, gutwika urumuri rwumuhondo ubururu, umubare muto wumwotsi wumukara, gutonyanga gutonyanga, impumuro ya paraffine.

2. Gukoresha cyane nibisohoka: Polypropilene yakusanyirijwe kumasoko ikoreshwa cyane cyane mubicuruzwa biboheye, bikoreshwa cyane, birashobora gukoreshwa mumifuka iboshywe, umugozi wo gupakira, umukandara uboshye, umugozi, umugongo winyuma nibindi, umusaruro wacyo wumwaka urenze Toni 800.000, bingana na 17% yumusaruro wose wa polypropilene.

PE Polyethylene polyethylene

PE ni plastike ya polyethylene, imiterere yimiti ihamye, mubisanzwe ikora imifuka yibiribwa nibintu bitandukanye, aside, alkali n amazi yumunyu birwanya isuri, ariko ntibigomba guhanagurwa cyangwa kubikwa hamwe nudukoko twinshi twa alkaline.

PPR

Bisanzwe copolymer polypropylene

1. Kubijyanye na Copolymer, copolymer yitwa Homonolymer.Kopolymer ikora koperimeri kuri monomers ebyiri cyangwa zirenga yitwa cololymer;

;2. Kubijyanye na Propylene na Ethene, PP-B na PP-R bihinduka Poly poly Copolymer;muri bo,

1) Ukoresheje uburyo bwa gazi ya kopolymerisiyasi yateye imbere, PE itunganijwe kandi igahuza polimerike imwe murwego rwa molekile ya PP, ibi bikoresho fatizo byitwa PP-R (random copolymerization polypropylene);

2) Ukoresheje PP na PE guhagarika copolymerisation, ibi bikoresho fatizo byitwa PP-B (guhagarika copolymerisation polypropylene)

PEX

Polyethylene ihujwe (PEX)

Umuyoboro uhuza polyethylene (PEX) imiyoboro

Imiyoboro isanzwe ya polyethylene (HDPE na MDPE), imiyoboro ya macromolecules ifite umurongo, ifite imbogamizi nini yo kutagira ubushyuhe buke no guhangana n’ibikurura, bityo imiyoboro isanzwe ya polyethylene isanzwe ntabwo ikwiranye no gutanga imiyoboro ifite ubushyuhe burenze 45 ℃."Kwambukiranya" ni uburyo bw'ingenzi bwo guhindura polyethylene.Imiterere ya macromolecular ya polyethylene ihinduka PEX hamwe nurusobe rwibice bitatu nyuma yo guhuza, ibyo bikaba bitezimbere cyane kurwanya ubushyuhe no kurwanya polyethylene.Hagati aho, gusaza kwayo, imiterere yubukanishi no gukorera mu mucyo byateye imbere cyane.Muri icyo gihe, iragwa imiti irwanya ruswa kandi ikoroha ya polyethylene.Hariho ubwoko butatu bwubucuruzi buboneka PEX.Umuyoboro wa PEXa umuyoboro PEXb umuyoboro wa PEXC

PEX ibiranga

Ubushyuhe buhebuje no kurwanya ubukonje, imbaraga nyinshi zumuriro mubushyuhe bwinshi:

Ubwiza buke bwo guhangana n'ubushyuhe bukabije:

Gushyushya udashonga:

Kurwanya ibidasanzwe bidasanzwe: Amakuru ya creep nifatizo ryingenzi mugushushanya ibicuruzwa no guhitamo ibikoresho bya injeniyeri.Ugereranije nibikoresho gakondo nk'ibyuma, imyitwarire itoroshye ya plastiki iterwa cyane nigihe cyo gupakira n'ubushyuhe.Ibikurura biranga umuyoboro wa PEX ni umwe mu miyoboro myiza cyane mu miyoboro isanzwe ya plastiki.Kurwanya ibidasanzwe bidasanzwe: Amakuru ya creep nifatizo ryingenzi mugushushanya ibicuruzwa no guhitamo ibikoresho bya injeniyeri.Ugereranije nibikoresho gakondo nk'ibyuma, imyitwarire itoroshye ya plastiki iterwa cyane nigihe cyo gupakira n'ubushyuhe.Ibikurura biranga umuyoboro wa PEX ni umwe mu miyoboro myiza cyane mu miyoboro isanzwe ya plastiki.

Ubuzima bwa serivisi zihoraho:

Umuyoboro wa PEX umaze gutsinda ikizamini cya 110 ℃ ubushyuhe, impeta ya 2.5MPa nigihe cya 8760h, dushobora kuvuga ko ubuzima bwacyo bukomeza kumyaka 50 kuri 70 ℃.
