Kusungirako madzi ndi mfundo ya HPMC cellulose ether

Imodzi mwa ntchito zazikulu za hydroxypropylmethylcellulose (HPMC) cellulose ethers ndi monga thickener ndi stabilizer mu zomangira, chakudya ndi zinthu chisamaliro munthu. Komabe, zimagwiranso ntchito yofunikira pakuwongolera kusungidwa kwa madzi muzinthu zambiri, kuphatikiza zomatira matailosi, ma grouts ndi matope opangidwa ndi simenti.

Kusunga madzi kumatanthauzidwa ngati kuthekera kwa chinthu kusunga kapena kusunga madzi owonjezera. Zinthu zikapanda madzi, zimatha kuyanika kapena kusweka, zomwe zimasokoneza magwiridwe ake onse.

Mfundo ya HPMC cellulose ether kuti ipititse patsogolo kusungirako madzi imachokera pamapangidwe ake apadera a maselo. HPMC cellulose ether ndi polysaccharide polima wopangidwa ndi mayunitsi a shuga olumikizidwa ndi β-(1,4) -glycosidic bond. Mulinso magulu a mbali ya hydroxypropyl ndi methyl, omwe amapatsa kusungunuka kwamadzi komanso kusunga madzi.

Pamene HPMC mapadi efa anawonjezedwa matope simenti ofotokoza, gulu lake hydroxypropyl adzakhala adsorbed pamwamba pa simenti particles. Izi zimapanga madzi ozungulira kuzungulira ma pellets, kuwateteza kuti asawume msanga. Panthawi imodzimodziyo, gulu la methyl limapereka cholepheretsa cholimba, kuteteza tinthu tating'ono ta simenti kuti tisamangirire kwambiri ndikupanga matrix wandiweyani. Izi zimathandiza kuti madzi agawidwe mosavuta mumatope onse, kuwongolera magwiridwe antchito ake, kusasinthika komanso magwiridwe antchito onse.

Kusunga madzi kumatha kuyeza pogwiritsa ntchito njira zosiyanasiyana, kuphatikiza kuyezetsa kuyamwa komanso kuyesa kwa centrifugation. Chiyeso choyamwa chimayesa kuchuluka kwa madzi omwe chinthu chingathe kusunga chikayikidwa mu vacuum. Mayeso a centrifuge amayesa kuchuluka kwa madzi omwe chinthu chingasungidwe chikagwidwa ndi mphamvu yapakati. Mayeserowa amathandiza kudziwa mphamvu ya HPMC cellulose ethers pokonza kusungidwa kwa madzi muzinthu zinazake.

Kuphatikiza pa kukonza kasungidwe ka madzi, ma ether a HPMC a cellulose amapereka maubwino ena pazomangira ndi ntchito zina. Imawongolera kumamatira ndikuchepetsa kutsika kwa zomatira matailosi, imapangitsa kuti matope opangidwa ndi simenti azigwira ntchito bwino, komanso amawonjezera kukhazikika kwa utoto ndi zokutira.

Mwachidule, ma ether a HPMC a cellulose amatenga gawo lofunikira pakukulitsa kusungidwa kwa madzi muzomangamanga ndi ntchito zina zambiri. Mapangidwe ake apadera a mamolekyu ndi kusungunuka kwa madzi kumapangitsa kuti ikhale yothandiza posungira madzi, zomwe zimabweretsa zabwino zambiri pakuchita kwa chinthu chomaliza.
