Ibanga le-PVC le-HPMC
I-PVCI-HPMC Hydroxypropyl Methylcellulose yeklasi yintlobo yepolymer enokusetyenziswa kakhulu kwaye isebenza kakhulu phakathi kwazo zonke iintlobo ze-cellulose. Isetyenziswa kakhulu kwiinkalo ezahlukeneyo zoshishino nakubomi bemihla ngemihla. Ibisoloko isaziwa ngokuba yi-"industrial MSG".
I-Hydroxypropyl methyl cellulose (HPMC) yenye yezona zinto ziphambili ezisasaza izinto kwishishini le-polyvinyl chloride (PVC). Ngexesha lokumiswa kwe-polymerization ye-vinyl chloride, inokunciphisa uxinzelelo lwe-interfacial phakathi kwe-VCM namanzi kwaye incede i-vinyl chloride monomers (VCM) ukuba isasazeke ngokulinganayo nangokuzinzileyo kwindawo enamanzi; ithintela amathontsi e-VCM ekudibaneni kwinqanaba lokuqala lenkqubo ye-polymerization; ithintela amasuntswana e-polymer ekudibaneni kwinqanaba lokugqibela lenkqubo ye-polymerization. Kwinkqubo ye-suspension polymerization, idlala indima yokusasazwa kunye nokukhuselwa. Indima embaxa yozinzo.
Kwi-polymerization yokumiswa kwe-VCM, amaconsi e-polymerization okuqala kunye nee-polymer particles eziphakathi nezisekupheleni kulula ukuzihlanganisa ekuqaleni, ngoko ke i-arhente yokukhusela ukusasazeka kufuneka yongezwe kwinkqubo ye-polymerization yokumiswa kwe-VCM. Kwimeko yendlela yokuxuba emiselweyo, uhlobo, uhlobo kunye nobungakanani be-dispersant ziye zaba zizinto eziphambili zokulawula iimpawu zee-particles ze-PVC.

Iimpawu
(1)Ubushushu bePolymerization: Ubushushu bePolymerization ngokusisiseko bumisela ubunzima obuphakathi beemolekyuli zePVC, kwaye i-dispersant ngokusisiseko ayinampembelelo kubunzima beemolekyuli. Ubushushu bejeli ye-dispersant buphezulu kunobushushu be-polymerization ukuqinisekisa ukusasazeka kwepolymer yi-dispersant.
(2) Iimpawu zamasuntswana: ububanzi bamasuntswana, imo, ubume, kunye nokusasazwa kwamasuntswana zizibonakaliso ezibalulekileyo zomgangatho we-SPVC, ezinxulumene noyilo lwe-agitator/reactor, umlinganiselo wamanzi-kwioyile, inkqubo yokusasazwa kunye nesantya sokuguqulwa kokugqibela kwe-VCM, apho inkqubo yokusasazwa ibaluleke kakhulu khona.
(3) Ukuxuba: Njengenkqubo yokusasazwa, inempembelelo enkulu kumgangatho we-SPVC. Ngenxa yobukhulu bamathontsi e-VCM emanzini, isantya sokuxuba siyanda kwaye ubungakanani bamathontsi buyehla; xa isantya sokuxuba siphezulu kakhulu, amathontsi aya kuhlangana aze achaphazele amasuntswana okugqibela.
(4) Inkqubo yokukhusela ukusasazeka: Inkqubo yokukhusela ikhusela amathontsi e-VCM kwinqanaba lokuqala lokusabela ukuze kuthintelwe ukudibana; i-PVC evelisiweyo ingena kumathontsi e-VCM, kwaye inkqubo yokusasazwa ikhusela ukuhlangana kwamathontsi alawulwayo, ukuze kufunyanwe amathontsi okugqibela e-SPVC. Inkqubo yokusasazwa yahlulwe yaba yinkqubo yokusasazwa ephambili kunye nenkqubo yokusasazwa encedisayo. I-dispersant ephambili ine-PVA, i-HPMC, njl.njl., echaphazela ukusebenza kwe-SPVC iyonke; inkqubo yokusasazwa encedisayo isetyenziselwa ukuphucula ezinye iimpawu zamathontsi e-SPVC.
(5) Inkqubo ephambili yokusasazwa: Azinyibiliki emanzini kwaye zizinzile amathontsi e-VCM ngokunciphisa uxinzelelo phakathi kwe-VCM namanzi. Okwangoku kushishino lwe-SPVC, izinto eziphambili zokusasaza yi-PVA kunye ne-HPMC. I-HPMC yodidi lwe-PVC ineengenelo zedosi ephantsi, uzinzo lobushushu kunye nokusebenza kakuhle kwe-SPVC njengeplastiki. Nangona ibiza kakhulu, isasetyenziswa kakhulu. I-HPMC yodidi lwe-PVC sisixhobo esibalulekileyo sokukhusela ukusasazeka kwi-PVC synthesis..
