PVC Grade HPMC

PVC kalasi HPMC Hydroxypropyl Methylcellulose ndi polima zosiyanasiyana ntchito kwambiri ndi ntchito kwambiri pakati pa mitundu yonse ya mapadi.Amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana komanso moyo watsiku ndi tsiku.Imatchedwa "Industrial MSG".

Hydroxypropyl methyl cellulose (HPMC) ndi amodzi mwa omwe amamwaza kwambiri mumakampani a polyvinyl chloride (PVC).Pa kuyimitsidwa polymerization wa vinilu kolorayidi, akhoza kuchepetsa interfacial mavuto pakati VCM ndi madzi ndi kuthandiza vinilu kolorayidi monomers (VCM) ndi uniformly ndi stably omwazika mu sing'anga amadzimadzi;imalepheretsa madontho a VCM kuti asaphatikizidwe mu gawo loyambirira la polymerization;kumalepheretsa particles polima kuti merging mu siteji mochedwa polymerization ndondomeko.Mu kuyimitsidwa polymerization dongosolo, amatenga mbali ya kubalalitsidwa ndi chitetezo The wapawiri udindo bata.

Mu VCM kuyimitsidwa polymerization, oyambirira polymerization m'malovu ndi pakati ndi mochedwa polima particles n'zosavuta coalesce pachiyambi, kotero kubalalitsidwa chitetezo wothandizila ayenera kuwonjezeredwa VCM kuyimitsidwa polymerization dongosolo.Pankhani ya njira yosakanikirana yosakanikirana, mtundu, chikhalidwe ndi kuchuluka kwa dispersant zakhala zofunikira kwambiri kuti zithetse makhalidwe a PVC particles.

Kufotokozera kwa Chemical

Gawo lazogulitsa:

Makhalidwe

(1) Kutentha kwa polymerization: Kutentha kwa polymerization kumatsimikizira kulemera kwa maselo a PVC, ndipo dispersant kwenikweni alibe mphamvu pa kulemera kwa maselo.The gel osakaniza kutentha kwa dispersant ndi apamwamba kuposa polymerization kutentha kuonetsetsa kubalalitsidwa kwa polima ndi dispersant.

(2) Tinthu makhalidwe: tinthu m'mimba mwake, morphology, porosity, ndi tinthu kugawa ndi zizindikiro zofunika SPVC khalidwe, amene akugwirizana ndi agitator / riyakitala kamangidwe, polymerization madzi ndi mafuta chiŵerengero, dongosolo kubalalitsidwa ndi mlingo womaliza kutembenuka kwa VCM, wa zomwe zimabalalika dongosolo ndizofunikira kwambiri .

(3) Kukondoweza: Monga njira yobalalitsira, imakhudza kwambiri mtundu wa SPVC.Chifukwa cha kukula kwa madontho a VCM m'madzi, kuthamanga kwachangu kumawonjezeka ndipo kukula kwa dontho kumachepa;pamene liwiro loyambitsa liri lalikulu kwambiri, madonthowo amaphatikizana ndikukhudza tinthu tating'ono tomaliza.

(4) Dongosolo lachitetezo chobalalika: Chitetezo chimateteza madontho a VCM koyambirira kwa zomwe zimachitika kuti asaphatikizidwe;ndi kwaiye PVC precipitates mu VCM m'malovu, ndi dongosolo kubalalitsidwa amateteza agglomeration wa ankalamulira particles, kuti apeze chomaliza SPVC particles.Dongosolo lobalalitsa limagawidwa munjira yayikulu yobalalika ndi njira yothandizira kubalalitsidwa.The dispersant chachikulu ali mkulu alcoholysis digiri PVA, HPMC, etc., amene amakhudza lonse ntchito SPVC;Njira yothandizira yobalalitsira imagwiritsidwa ntchito kukonza mawonekedwe a tinthu ta SPVC.

(5) Njira yayikulu yobalalitsira: Imasungunuka m'madzi ndikukhazikika madontho a VCM pochepetsa kusagwirizana pakati pa VCM ndi madzi.Pakali pano mu makampani a SPVC, ofalitsa akuluakulu ndi PVA ndi HPMC.PVC kalasi HPMC ali ubwino mlingo otsika, bata matenthedwe ndi bwino plasticizing ntchito SPVC.Ngakhale kuti ndi yokwera mtengo, imagwiritsidwabe ntchito kwambiri.PVC grade HPMC ndi yofunikira yoteteza kubalalika mu kaphatikizidwe ka PVC.

Kupaka

Kunyamula kokhazikika ndi 25kg / ng'oma 

20'FCL: matani 9 okhala ndi palletized; matani 10 opanda palletized.

40'FCL: matani 18 okhala ndi palletized; matani 20 opanda palletized.

Posungira:

Sungani pamalo ozizira, owuma osapitirira 30 ° C ndi kutetezedwa ku chinyezi ndi kukanikiza, popeza katunduyo ndi thermoplastic, nthawi yosungira sikuyenera kupitirira miyezi 36.

Zolemba pachitetezo:                                                                   

Zomwe zili pamwambazi zikugwirizana ndi zomwe timadziwa, koma musamatsutse makasitomala kuti aziyang'ana zonse mwamsanga mutalandira.Kuti mupewe kupangidwa kosiyanasiyana ndi zida zosiyanasiyana, chonde yesaninso zambiri musanagwiritse ntchito.
