HPMC y'urwego rwa PVC

PVCHPMC Hydroxypropyl Methylcellulose yo mu rwego rwo hejuru ni ubwoko bwa polymer bufite akamaro kanini kandi bufite umusaruro mwiza cyane mu bwoko bwose bwa cellulose. Ikoreshwa cyane mu nzego zitandukanye z'inganda no mu buzima bwa buri munsi. Yamenyekanye nka "MSG y'inganda".

Hydroxypropyl methyl cellulose (HPMC) ni imwe mu nganda zikora polyvinyl chloride (PVC). Mu gihe cyo gupima vinyl chloride, ishobora kugabanya imbaraga hagati ya VCM n'amazi no gufasha monomer za vinyl chloride (VCM) gukwirakwira neza mu mazi; ibuza ibitonyanga bya VCM kwihuza mu ntangiriro z'uburyo bwo gupima polymer; ibuza uduce twa polymer kwihuza mu cyiciro cya nyuma cy'uburyo bwo gupima polymer. Muri sisitemu yo gupima polymer, igira uruhare mu gukwirakwiza no kurinda. Uruhare rubiri rw'ubudahangarwa.

Mu gupima polymer ya VCM, ibitonyanga bya polymeri bya mbere n'uduce twa polymeri two hagati n'utwo nyuma biroroshye guhuzwa mu ntangiriro, bityo ikintu kirinda gukwirakwira kigomba kongerwa muri sisitemu ya VCM yo gupima polymeri. Mu gihe habayeho uburyo bwo kuvanga buhamye, ubwoko, imiterere n'ingano y'ibicuruzwa bikwirakwiza byabaye ibintu by'ingenzi bigenzura imiterere y'uduce twa PVC.

Ibisobanuro by'imiti

Ingano y'ibicuruzwa:

Ibiranga

(1)Ubushyuhe bwa polymerization: Ubushyuhe bwa polymerization bugena uburemere mpuzandengo bwa molekile ya PVC, kandi molekile nta ngaruka igira ku buremere bwa molekile. Ubushyuhe bwa gel bw'umukara uri hejuru y'ubushyuhe bwa polymerization kugira ngo polymer ikwirakwizwe n'umukara.

(2) Ibiranga uduce: umurambararo w'uduce, imiterere yatwo, porosity, n'ikwirakwizwa ry'uduce ni ibipimo by'ingenzi byerekana ubuziranenge bwa SPVC, bifitanye isano n'igishushanyo mbonera cya agitator/reactor, polymerization y'amazi na peteroli, sisitemu yo gukwirakwiza hamwe n'igipimo cya nyuma cyo guhindura VCM, aho sisitemu yo gukwirakwiza ari ingenzi cyane.

(3) Gukangura: Kimwe n'uburyo bwo gukwirakwiza amazi, bigira ingaruka zikomeye ku bwiza bwa SPVC. Kubera ingano y'ibitonyanga bya VCM mu mazi, umuvuduko wo gukangura uriyongera kandi ingano y'ibitonyanga iragabanuka; iyo umuvuduko wo gukangura uri hejuru cyane, ibitonyanga biziteranya bikagira ingaruka ku tunyangingo twa nyuma.

(4) Sisitemu yo kurinda gukwirakwiza: Sisitemu yo kurinda ibitonyanga bya VCM mu ntangiriro z'ingaruka kugira ngo birinde guhuzwa; PVC yakozwe ihita mu bitonyanga bya VCM, naho sisitemu yo gukwirakwiza irinda guhurira kw'ibitonyanga bigenzurwa, kugira ngo haboneke ibitonyanga bya nyuma bya SPVC. Sisitemu yo gukwirakwiza igabanyijemo sisitemu nyamukuru yo gukwirakwiza n'isitemu y'inyongera yo gukwirakwiza. Imashini nyamukuru yo gukwirakwiza ifite PVA, HPMC, nibindi byinshi, bigira ingaruka ku mikorere rusange ya SPVC; sisitemu y'inyongera yo gukwirakwiza ikoreshwa mu kunoza imiterere imwe n'imwe y'ibitonyanga bya SPVC.

(5) Sisitemu nyamukuru yo gukwirakwiza: Bishobora gushonga mu mazi kandi bigatuza ibitonyanga bya VCM binyuze mu kugabanya imbaraga hagati ya VCM n'amazi. Muri iki gihe mu nganda za SPVC, ibikoresho by'ingenzi byo gukwirakwiza ni PVA na HPMC. HPMC yo mu rwego rwa PVC ifite ibyiza byo kuba ingano nto, kudahindagurika kw'ubushyuhe ndetse no gukora neza kwa SPVC mu buryo bwa pulasitiki. Nubwo ihenze cyane, iracyakoreshwa cyane. HPMC yo mu rwego rwa PVC ni igikoresho cy'ingenzi cyo kurinda gukwirakwiza mu gukora PVC..
