Polyvinyl chloride (pvc)

Mukuyimitsidwa polymerization wa vinyl chloride, omwe amamwazikulu amakhudzanso chinthucho, pvc uler, komanso pazinthu zake ndi zinthu zake. Hydroxypropyll methylcelulose imathandizira kukonza kukhazikika kwa matenthedwe ndikuwongolera kagawo ka TVC PVC imiteni yopangidwa ndi hydroxypylyulose ya methylcellulose yokha yokhayo yomwe ili ndi miyezo yadziko lapansi, komanso imatha kukhala ndi zinthu zakuthupi zamayiko, komanso zomwe zimapangitsa kuti pakhale zopanda pake.

PVC ndi chokhalitsa cholimba komanso chokhalitsa chomwe chingagwiritsidwe ntchito m'njira zosiyanasiyana, zomwe zingatheke kapena kusinthasintha, zoyera kapena zakuda komanso mitundu yosiyanasiyana pakati.

Popanga zitsulo zopangidwa, monga polyvinyl chloride (pvc), polyvinylidene chloride, ndi ena owonjezera, omwe amagwiritsidwa ntchito polymerization kwambiri ndipo ayenera kukhala otayidwa mokongola kwambiri. Monga osungunuka madzi osungunuka, hydroxypropyl mankhwala ogulitsa ali ndi ntchito yabwino kwambiri ndikugwira ntchito monga kuteteza othandizira colloidal. Hydroxypypyl methylcellulose imatha kupewa bwino tinthu tambiri a polymeric kuti atulutse komanso kuchitika. Kuphatikiza apo, ngakhale ma hydroxypropyll methylcellulose ndi polymer yamadzi, imatha kusungunuka pang'ono mu hydrophobic monomers ndipo imatha kuwonjezera chidwi chopanga ma polymer.

Zogulitsa za HPMC HPMC zitha kusintha ndi zinthu zotsatirazi mu PVC:

Ogwiritsa ntchito mopitilira muyeso.

· Kuwongolera kukula kwa tinthu tagawika

Chikhalidwe champhamvu
