Suspension Polymerization of (HPMC) Hydroxypropyl Methylcellulose kushandiswa kwePVC

Suspension polymerization yeHydroxypropyl Methylcellulose (HPMC) haisi nzira yakajairika yekugadzira polyvinyl chloride (PVC). Pane kudaro, kumiswa kwepolymerization kunowanzo shandiswa kugadzira PVC pachayo kana mamwe vinyl polymers.

Nekudaro, HPMC inogona kushandiswa muPVC maumbirwo sechinhu chinowedzera kugadzirisa akasiyana siyana ePVC komboni kana yekupedzisira PVC chigadzirwa. Heano maitiro HPMC anogona kushandiswa muPVC maapplication:

1. Impact Modifier:

• HPMC inogona kushandiswa seyakagadzirisa gadziriso muPVC maumbirwo ekuvandudza kuoma uye kukanganisa kuramba kwePVC zvinhu. Nekubatanidza HPMC zvimedu muPVC matrix, simba rekukanganisa rechigadzirwa chekupedzisira rinogona kukwidziridzwa, zvichiita kuti ive yakakodzera kune maapplication anoda kusimba uye kusimba.

2. Kugadzirisa Rubatsiro:

• HPMC inogona kuita seyamuro yekugadzirisa muPVC kusanganisa, ichibatsira kuvandudza kuyerera zvivakwa uye processability yePVC inonyungudika panguva yekuwedzeredza, kuumba, kana kuita karenda. Izvi zvinogona kukonzera kugadzirisa kwakapfava, kuderedzwa kwekufa kuvaka-up, uye kugadziridzwa kwepamusoro kupedzisa kwekupedzisira PVC zvigadzirwa.

3. Rheology Modifier:

• HPMC inogona kushanda se rheology modifier muPVC maumbirwo, ichipesvedzera viscosity uye kuyerera maitiro eiyo PVC komboni. Nekugadzirisa iyo yekumisikidza uye mamorekuru huremu hweHPMC, iyo rheological zvimiro zvePVC inonyungudika inogona kugadzirwa kuti isangane nezvinodiwa zvekugadzirisa uye maitiro ekuita.

4. Anti-Blocking Agent:

• HPMC inogona kushandiswa seanopokana-kuvharira mumiririri mumafirimu ePVC nemashiti kudzivirira kuti asanamatirana panguva yekuchengetedza kana kutakura. Nekubatanidza HPMC zvimedu muPVC matrix, maitiro ePVC zvinhu kuvhara kana kunamatira pachezvayo anogona kuderedzwa, kuvandudza kubata uye kushandiswa.

5. Plasticizer Kuenderana:

• HPMC inogona kusimudzira kuenderana kweplasticizers nePVC maumbirwo, kufambisa kupararira uye kugovera mamorekuru eplasticizer mukati mePVC matrix. Izvi zvinogona kutungamira mukuvandudzika kuchinjika, kurebesa, uye kuderera-kupisa kwePVC zvinhu, kunyanya mumashandisirwo anoda kuchinjika uye kupfava.

6. Flame Retardant Synergist:

• HPMC inogona kuita se synergist mumirazvo inodzoreredza maumbirwo ePVC, ichiwedzera kudzoreredza kwemurazvo uye kuramba moto kwePVC zvinhu. Nekusimudzira kuumbwa kwechar uye kuderedza kupisa kuburitswa, HPMC inogona kuvandudza mashandiro emoto ezvigadzirwa zvePVC mumashandisirwo akasiyana siyana, senge zvekuvaka uye tambo dzemagetsi.

Muchidimbu, nepo HPMC isingawanzo kushandiswa mukumiswa kwepolymerization yePVC, inogona kushandiswa seyekuwedzera muPVC maumbirwo ekugadzirisa zvinhu zvakaita sesimba rekukanganisa, maitiro ekugadzirisa, rheology, anti-blocking maitiro, kuenderana kweplasticizer, uye kunonoka kwemurazvo. . Hurukuro hwayo hunoita kuti ive chinhu chakakosha mukugadzira PVC makomputa ane akarongedzerwa zvivakwa uye maitiro ekuita.
