QualiCell Hydroxypropyl Methyl Cellulose HPMC zvigadzirwa zvinogona kuvandudzwa neinotevera zvivakwa muPVC:
·inonyanya kushandiswa suspending agents.
·Inodzora saizi yezvidimbu uye kugoverwa kwadzo
·Inopesvedzera porosity
· Inotsanangura huremu hwakawanda hwePVC.
Cellulose ether yePolyvinyl Chloride (PVC)
Polyvinyl Chloride (PVC) inopfumisa uye inoshanda zvakasiyana-siyana thermoplastic polima inoshandiswa zvakanyanya mukuvaka uye kuvaka indasitiri kugadzira magonhi nemahwindo profiles, pombi (kunwa uye tsvina yemvura), waya uye tambo yekuvharisa, midziyo yekurapa, nezvimwewo. Ndiyo yechitatu pasi rose thermoplastic. zvinhu nehuwandu mushure me polyethylene uye polypropylene.
PVC inoshandiswa zvakanyanya mumhando dzakasiyana-siyana dzemaindasitiri, tekinoroji uye zvemazuva ese zvinosanganisira kushandiswa kwakapararira mukuvaka, kutakura, kurongedza, zvemagetsi / zvemagetsi uye zvehutano.
Mukumiswa kwepolymerization yevinyl chloride, iyo yakapararira sisitimu ine chekuita chakananga pachigadzirwa, PVC resin, uye pamhando yekugadziriswa kwayo uye zvigadzirwa. Hydroxypropyl MethylCellulose inobatsira kuvandudza kugadzikana kwekupisa kweresin uye kutonga kugovera saizi yechikamu (nemamwe mazwi, gadzirisa PVC density), uye huwandu hwayo hunoita 0.025% -0.03% yekugadzirwa kwePVC. PVC resin yakagadzirwa kubva kumhando yepamusoro Hydroxypropyl MethylCellulose haingogone chete kuve nechokwadi mutsara wekuita nemaitiro epasirese, asi zvakare inogona kuve yakanaka inooneka zvimiro zvemuviri, yakanakisa particle zvimiro uye yakanakisa kunyungudika rheological maitiro.
PVC chinhu chakasimba uye chinogara kwenguva refu chinogona kushandiswa mumhando dzakasiyana dzekushandisa, ingave yakaoma kana inochinjika, chena kana dema uye dzakasiyana siyana dzemavara pakati.
Mukugadzira maresin ekugadzira, akadai sepolyvinyl chloride (PVC), polyvinylidene chloride, uye mamwe macopolymers, suspension polymerization ndiyo inonyanya kushandiswa uye inofanirwa kunge isingachinji hydrophobic monomers yakamiswa mumvura. Semapolima anonyungudika nemvura, Hydroxypropyl MethylCellulose chigadzirwa chine yakanakisa chiitiko chepamusoro uye inoshanda seyekudzivirira colloidal agents. Hydroxypropyl MethylCellulose inogona kudzivirira zvinobudirira zvimedu zvepolymeric kubva mukugadzira uye agglomeration. Uyezve, kunyangwe Hydroxypropyl MethylCellulose iri mvura soluble polymer, inogona kunyungudika zvishoma mumahydrophobic monomers uye inogona kuwedzera monomer porosity yekugadzirwa kwepolymeric particles.
