Kumiswa Polymerization yeHydroxypropyl Methylcellulose muPVC

Kumiswa kwepolymerization yeHydroxypropyl Methylcellulose (HPMC) muPolyvinyl Chloride (PVC) haisi yakajairika maitiro.HPMC inonyanya kushandiswa sechinhu chinowedzera kana kushandura muPVC maumbirwo kwete semumiriri wepolymerization.

Nekudaro, HPMC inogona kuunzwa muPVC maumbirwo kuburikidza nekugadzirisa maitiro apo inosanganiswa nePVC resin uye zvimwe zvinowedzera kuti iwane chaiyo zvivakwa kana mashandiro ekuwedzera.Mumamiriro ezvinhu akadaro, HPMC inoshandisa mabasa akasiyana-siyana akadai semukobvu, binder, stabilizer, kana rheology modifier.

Heano mamwe mabasa akajairika eHPMC muPVC maumbirwo:

1. Thickener uye Rheology Modifier: HPMC inogona kuwedzerwa kuPVC maumbirwo ekugadzirisa viscosity, kugadzirisa maitiro ekugadzirisa, uye kuwedzera kuyerera kwepolymer kunyungudika panguva yekugadzirisa.
2. Binder uye Adhesion Promoter: HPMC inovandudza kunamatira pakati pePVC particles nezvimwe zvinowedzera mukugadzirisa, kukurudzira homogeneity uye kugadzikana.Inobatsira kubatanidza zvinhu pamwe chete, kuderedza kupatsanurwa uye kuvandudza kushanda kwese kwePVC makomisheni.
3. Stabilizer uye Plasticizer Compatibility: HPMC inoshanda seyakagadzika muPVC maumbirwo, ichipa kuramba kuderera kwekupisa, UV mwaranzi, uye oxidation.Inowedzerawo kuenderana kweplasticizers nePVC resin, inovandudza kushanduka, kusimba, uye mamiriro ekunze ezvigadzirwa zvePVC.
4. Impact Modifier: Mune mamwe maPVC maapplication, HPMC inogona kuita senge inogadzirisa, kuvandudza kuoma uye kukanganisa kuramba kwePVC zvigadzirwa.Inobatsira kuwedzera ductility uye kutsemuka kuomarara kwePVC komisheni, kuderedza mukana wekutadza kutadza.
5. Filler uye Reinforcement Agent: HPMC inogona kushandiswa senge yekuzadza kana yekusimbisa mumiriri muPVC maumbirwo ekuwedzera ma mechanic zvivakwa senge tensile simba, modulus, uye dimensional kugadzikana.Inovandudza kuita kwese uye kurongeka kwePVC zvigadzirwa.

nepo HPMC isingawanzo kuita polymerized nePVC kuburikidza nekumiswa kwepolymerization, inowanzounzwa muPVC maumbirwo kuburikidza nekugadzirisa maitiro kuti uwane chaiwo ekuwedzera mashandiro.Sekuwedzera kana kugadzirisa, HPMC inobatsira kune dzakasiyana siyana zvigadzirwa zvePVC, zvichiita kuti ive yakakodzera kune dzakasiyana siyana dzekushandisa mumaindasitiri akadai sekuvaka, mota, kurongedza, uye hutano hwehutano.
