I-Polyvinyl Chloride (PVC)

Imikhiqizo ye-QualiCell Hydroxypropyl Methyl Cellulose HPMC ingathuthuka ngalezi zakhiwo ezilandelayo ku-PVC:
·avamise ukusetshenziswa kakhulu ama-suspending agents.
·Ilawula usayizi wezinhlayiyana nokusatshalaliswa kwazo
·Ithonya i-porosity
·Ichaza isisindo esikhulu se-PVC.

I-Cellulose ether ye-Polyvinyl Chloride (PVC)

I-Polyvinyl Chloride (PVC) iyi-polymer eyongayo futhi eguquguqukayo ye-thermoplastic esetshenziswa kabanzi embonini yokwakha neyokwakha ukuze kukhiqizwe amaphrofayili eminyango namafasitela, amapayipi (ukuphuza namanzi angcolile), ukufakwa kwezintambo nokufakwa kwamakhebula, imishini yezokwelapha, njll. Ingowesithathu ngobukhulu emhlabeni we-thermoplastic. impahla ngevolumu ngemuva kwe-polyethylene ne-polypropylene.

I-PVC isetshenziswa kabanzi kulo lonke uhla olubanzi lwezinhlelo zokusebenza zezimboni, ezobuchwepheshe nezansuku zonke ezihlanganisa ukusetshenziswa okusabalele ezakhiweni, ezokuthutha, zokupakisha, zikagesi/i-elekthronikhi nezokunakekelwa kwezempilo.

I-Polyvinyl-Chloride-(PVC)

Ekumisweni kwe-polymerization ye-vinyl chloride, uhlelo oluhlakaziwe lunomthelela oqondile kumkhiqizo, i-PVC resin, kanye nekhwalithi yokucubungula kwayo nemikhiqizo.IHydroxypropyl MethylCellulose isiza ukuthuthukisa ukuzinza okushisayo kwe-resin nokulawula ukusabalalisa usayizi wezinhlayiyana (ngamanye amazwi, lungisa ukuminyana kwe-PVC), futhi inani layo libalelwa ku-0.025% -0.03% wokukhiqizwa kwe-PVC.I-PVC resin eyenziwe ngekhwalithi ephezulu ye-Hydroxypropyl MethylCellulose ayigcini nje ngokuqinisekisa umugqa wokusebenza onamazinga omhlaba, kodwa futhi ingaba nezakhiwo ezibonakalayo ezibonakalayo ezinhle, izakhiwo ezinhle kakhulu zezinhlayiya kanye nokuziphatha okuhle kakhulu kwe-rheological okuncibilika.

I-PVC iyinto ehlala isikhathi eside futhi ehlala isikhathi eside engasetshenziswa ezinhlelweni ezihlukahlukene, kungaba eqinile noma evumelana nezimo, emhlophe noma emnyama kanye nohlu olubanzi lwemibala phakathi.

Ekukhiqizeni ama-synthetic resins, njenge-polyvinyl chloride (PVC), i-polyvinylidene chloride, namanye ama-copolymers, i-suspension polymerization iyona esetshenziswa kakhulu futhi kufanele ibe ama-hydrophobic monomers angaguquki amiswe emanzini.Njengama-polymers ancibilika emanzini, umkhiqizo we-Hydroxypropyl MethylCellulose unomsebenzi omuhle kakhulu wangaphezulu futhi usebenza njengama-ejenti e-colloidal avikelayo.IHydroxypropyl MethylCellulose ingavimbela ngempumelelo izinhlayiya ze-polymeric ekukhiqizeni nasekuhlanganiseni.Ngaphezu kwalokho, nakuba i-Hydroxypropyl MethylCellulose iyi-polymer encibilikayo emanzini, ingancibilika kancane kuma-hydrophobic monomers futhi ingakhuphula i-monomer porosity yokukhiqizwa kwezinhlayiya ze-polymeric.
