Pvc grass hpmc

PvcGulu la HPMC hydroxpyll ndi mitundu ya polymer yomwe imagwiritsidwa ntchito kwambiri komanso ntchito zapamwamba kwambiri pakati pa cellulose. Amagwiritsidwa ntchito kwambiri m'minda yosiyanasiyana ya mafakitale ndi moyo watsiku ndi tsiku. Zakhala zikudziwika kuti "mafakitale a Msg".

Hydroxypropyl Medielose (HPMC) ndi amodzi mwa omwe amamwazikulu omwazikana mu polyvinyl chloride (pvc). Pa nthawi yoyatsidwa ya yini ya vinyl chloride, imatha kuchepetsa mavuto a VCM ndi kumadzi ndikuthandizira vinyl chloride molmor. imalepheretsa madontho a VCM kuchokera kuzolowera koyambirira kwa njira yolatira; Imalepheretsa ma polymer tinthu tambiri poyerekeza kumapeto kwa njira ya polymerization. Mukuyimitsidwa dongosolo la ma polymerization, limakonda kubalalitsa ndikutchinjiriza gawo lambiri.

Mu vcm kuyimitsidwa polymerization, madontho oyambilira a polymerization ndi molymes polymes ndiosavuta kuti agwirizane pa chiyambi, kotero nthumwi yotchinga iyenera kuwonjezeredwa ku ma polymerization polymerization. Pankhani ya njira yosakanikirana yokhazikika, mtundu, chilengedwe ndi kuchuluka kwa omwe amabalalitsa akhala zinthu zofunika kwambiri kuti athetse mawonekedwe a PVC.

Kutanthauzira kwamankhwala

Gawo Logulitsa:

Machitidwe

(1)Kutentha kwa polymerization: Kutentha kwa polymerization kumatsimikizira kuchuluka kwa ma pvc, ndipo omwe amamwa anzawo alibe mphamvu pa kunenepa. Kutentha kwa gel kuwuma ndikokwera kuposa kutentha kwa polymerization kuonetsetsa kuti kubalaku kwa polymer ndi obalalitsa.

. Ndi mtundu uti wobalalika makamaka.

(3) Kuyambitsa: Monga kubalalika, kumakhudza kwambiri spvc. Chifukwa cha kukula kwa madontho a VCM m'madzi, liwiro losangalatsa limakwera ndipo kukula kwa kalo kamachepa; Liwiro losangalatsa likakwera kwambiri, madontho amaphatikizika ndikukhudza tinthu tating'onoting'ono.

. PVC yopangidwa ndi vcm m'malovu a VCM, ndipo kubalalitsidwa kumateteza kuphatikizika kwa tinthu tating'onoting'ono, kuti tipeze tinthu totsiriza. Dongosolo lobalalika limagawidwa mu dongosolo lalikulu lobalalitsa ndi othandizira obalalika. Banja lalikulu limakhala ndi degraulysine degree PVA, HPMC, etc., yomwe imakhudza ntchito yonse ya SPVC; Othandizira ofalitsa owonjezera amagwiritsidwa ntchito kukonza mikhalidwe ina ya spvc tinthu.

. Pakadali pano mu malonda a SPVC, omwe amamwazikulu ndi PVP ndi HPMC. PVC kalasi hpmc ali ndi maubwino a Mlingo wotsika, kukhazikika kwamafuta ndi ntchito yabwino kwambiri ya spvc. Ngakhale zili zokwera mtengo, zimagwiritsidwabe ntchito kwambiri. Pvc grass hpmc ndi yofunika yobayira othandizira ku PVC Synthesis.

Kusungira:

Sungani pamalo ozizira, owuma pansi pa 30 ° C ndikutetezedwa kunyozedwa ndi kukanikiza, popeza kuti katunduyo ndi wa thermoplastic, nthawi yosungirako sayenera kupitirira miyezi 36.

Zolemba Zotetezeka:

Zomwe zili pamwambazi zikufanana ndi chidziwitso chathu, koma musatikwaniritse makasitomala mosamala nthawi yomweyo pakulandila. Pofuna kupewa mawonekedwe osiyanasiyana komanso zinthu zosiyanasiyana zopangira, chonde werengani musanagwiritse ntchito.
