Kumiswa Polymerization yeHydroxyPropyl Methylcellose muPVC

Kumiswa Polymerization yeHydroxyPropyl methylcellose (HPMC) muPolyvinyl chloride (PVC) haisi chiitiko chakajairika. HPMC inonyanya kushandiswa seyakawedzera kana modifier muPVC mafomu kwete sepamhepo yePolymeration.

Nekudaro, HPMC inogona kuunzwa muPVC mafambiro kuburikidza nemaitiro ekuwedzera apo iyo inosanganiswa nePVC resin uye zvimwe zvinowedzera kuti uwane zvivakwa kana zvinoitika zvekuita. Muzviitiko zvakadaro, HPMC inoshandisa mabasa akasiyana-siyana senge tizizeri, binder, stabilizer, kana rheology modifier.

Heano mamwe mabasa akajairika eHPMC mune PVC mafomu:

1. Thickener uye rheology modifier: HPMC inogona kuwedzerwa kune PVC mafambiro ekugadzirisa zvevasikisi, kugadzirisa maitiro ekugadzirisa, uye kuwedzera kuyerera kwenzvimbo yePolymer inonyungudika panguva yekugadzirisa.
2. Binder uye Adhemon Promoter: HPMC inovandudza kudiwa pakati pePVC zvimedu uye zvimwe zvinowedzera mukuumbwa, kusimudzira homogeneity uye kugadzikana. Inobatsira kusunga zvishandiso pamwe chete, kuderedza segregation uye kuvandudza kuita kwese kwePVC makomputa.
3. STabilizer uye Plasticze Kuenderana: HPMC inoita seStabilizer muPVC mafomu, inopa kuramba kuyamwisa, UV radiation, uye oxidation. Izvo zvinowedzerawo kuwirirana kwepurasitiki nePVC resin, kuvandudza kuchinjika, kusimba, uye zvakasarudzika zvePVC zvigadzirwa.
4. IMPACT Modifier: Mune zvimwe zviitiko zvePVC, HPMC inogona kuita seyakavanzika modifier, kuvandudza kuoma uye kukanganisa kwePVC zvigadzirwa. Iyo inobatsira kuwedzera iyo tuctlity uye kupwanyika kuomarara kwePVC makomputa epvc, kuderedza mukana wekutadza kweBrittle.
5. Filler uye kusimbisa mumiririri: HPMC inogona kushandiswa semutengesi kana kusimbisa mumiririri muPVC mafambiro ekusimudzira manhamba akadai seanosimbisa simba, Modulus, uye kudzikama. Iyo inovandudza maitiro ese ekuita uye kutendeseka kwePVC zvigadzirwa.

Nepo HPMC isiri iyo polymerized nePVC kuburikidza nekumiswa polpsion polmerization, inowanzotumirwa muPVC mafambiro kuburikidza nemaitiro ekuwedzera kuti awane kunyatsoita basa rekuita. Sezvinowedzera kana modifier, HPMC inobatsira zvakasiyana siyana zvePVC zvigadzirwa, zvichiita kuti vakwanise kuve vakakwana kuti vawedzere maindasitiri akadai sekuvaka, automotive, kutakura uye hutano.
