PVC Grade HPMC
Ibakala lePVC iHPMC Hydroxypropyl Methylcellulose luhlobo lwepolymer olusetyenziswa kakhulu kunye nokusebenza okuphezulu phakathi kwazo zonke iintlobo zeselulosi.Isetyenziswa ngokubanzi kwiinkalo ezahlukeneyo zoshishino kunye nobomi bemihla ngemihla.Ibisoloko isaziwa “njenge-MSG yamashishini”.
IHydroxypropyl methyl cellulose (HPMC) yenye yezinto eziphambili zokusasazi kwishishini lepolyvinyl chloride (PVC).Ngexesha lokumiswa kwepolymerization ye-vinyl chloride, inokunciphisa ukunyanzeliswa kwe-interfacial phakathi kwe-VCM kunye namanzi kwaye incede i-vinyl chloride monomers (VCM) ifane kwaye ihlakazeke ngokuzinzileyo kwindawo enamanzi;ikhusela amaconsi eVCM ekudibaneni kwinqanaba lokuqala lenkqubo ye-polymerization;ikhusela amasuntswana epolymer ekudibaneni kwinqanaba lokugqibela lenkqubo yepolymerization.Kwinkqubo yokumiswa kwepolymerization, idlala indima yokusabalalisa kunye nokukhusela Indima ebini yokuzinza.
Kwi-polymerization ye-VCM yokumiswa, i-droplets yokuqala ye-polymerization kunye ne-middle and late particles ye-polymer kulula ukudibanisa ekuqaleni, ngoko ke i-agent yokukhusela i-dispersion kufuneka yongezwe kwinkqubo ye-polymerization ye-VCM.Kwimeko yendlela yokuxuba ehleliweyo, uhlobo, uhlobo kunye nesixa se-dispersant ziye zaba zizinto eziphambili zokulawula iimpawu zePVC.

Iimpawu
(1) Ubushushu bepolymerization: Ubushushu bepolymerization bumisela ngokusisiseko ubunzima bemolekyuli yePVC, kwaye i-disperant ayinayo impembelelo kubunzima bemolekyuli.Ubushushu be-gel ye-dispersant buphezulu kunobushushu be-polymerization ukuqinisekisa ukusasazeka kwepolymer yi-dispersant.
(2) Iimpawu ze-Particle: i-particle diameter, i-morphology, i-porosity, kunye nokusabalalisa i-particle zizibonakaliso ezibalulekileyo zekhwalithi ye-SPVC, ehambelana ne-agitator / i-reactor design, i-polymerization yamanzi-to-oyile ratio, inkqubo yokusabalalisa kunye nokuguqulwa kokugqibela kwe-VCM, eyona nto ibaluleke kakhulu inkqubo yokusasaza .
(3) Ukuvuselela: Njengenkqubo yokusabalalisa, inempembelelo enkulu kumgangatho we-SPVC.Ngenxa yobukhulu bamaconsi eVCM emanzini, isantya esishukumisayo siyanda kwaye ubukhulu be-droplet buyancipha;xa isantya esishukumisayo siphezulu kakhulu, amaconsi aya kudibanisa kwaye achaphazele amasuntswana okugqibela.
(4) Inkqubo yokukhusela ukusabalalisa: Inkqubo yokukhusela ikhusela amaconsi eVCM kwinqanaba lokuqala lokuphendula ukuphepha ukudibanisa;i-PVC eveliswayo iyancipha kwi-droplets ye-VCM, kwaye inkqubo yokusabalalisa ikhusela i-agglomeration yeengqungquthela ezilawulwayo, ukuze ufumane iinqununu ze-SPVC zokugqibela.Inkqubo ye-dispersion yahlulwe kwi-dispersion system kunye ne-axiliary dispersion system.I-dispersant engundoqo ine-high alcoholysis degree PVA, HPMC, njl., echaphazela ukusebenza ngokubanzi kwe-SPVC;inkqubo encedisayo yokusabalalisa isetyenziselwa ukuphucula ezinye iimpawu zamasuntswana e-SPVC.
(5) Inkqubo ephambili yokusabalalisa: Ziyi-soluble yamanzi kwaye zizinzisa amathontsi eVCM ngokunciphisa ukuxhatshazwa kobuso phakathi kweVCM kunye namanzi.Okwangoku kwishishini le-SPVC, ezona zisasazo ziphambili yiPVA kunye neHPMC.PVC grade HPMC has iinzuzo idosi ephantsi, uzinzo thermal kunye nokusebenza kakuhle plasticizing of SPVC.Nangona ixabisa kakhulu, isasetyenziswa ngokubanzi.PVC grade HPMC i arhente yokhuseleko ukusasazwa ebalulekileyo PVC synthesis.
