Hydroxypropyl methyl cellulose HPMC makamaka imakhala ndi ma viscosity atatu, HPMC-100000, HPMC-150000, ndi HPMC-200000 viscosity. Kawirikawiri, hydroxypropyl methyl cellulose yokhala ndi viscosity ya 100,000 imagwiritsidwa ntchito popanga mkati ndi kunja kwa khoma putty powder. Ma cellulose ali ndi viscosity ya 200,000 ndipo amagwiritsidwa ntchito pomanga zinthu monga matope owuma, matope amwala osavuta, matope a diatom, ndi zokutira makoma. Mankhwalawa ali ndi zotsatira zabwino zosungira madzi, zotsatira zabwino za thickening, khalidwe lokhazikika komanso mtengo wololera.
Hydroxypropyl methylcellulose HPMC imagwiritsidwa ntchito kwambiri popanga zida zomangira. Ma cellulose ambiri amatha kugwiritsidwa ntchito ngati retarder, chosungira madzi, thickener ndi binder. Ma cellulose ether amatenga gawo lofunikira mumatope osakaniza owuma, matope otsekemera akunja, matope odziyika okha, zomatira zomatira za ufa wouma, matailosi a ceramic omangira matope owuma a ufa, matope opangira ntchito kwambiri, mkati ndi kunja kwa ming'alu. khoma putty, etc. , madzi owuma osakaniza matope, gypsum pulasitala, kusala whitening wothandizira, woonda wosanjikiza mfundo ndi zipangizo zina. Zimakhudza kwambiri kusungidwa kwa madzi, zofunikira za madzi, kumveka bwino, kuchedwetsa komanso kugwira ntchito kwa makina a stucco. Ma cellulose ether omwe amagwiritsidwa ntchito kwambiri pantchito yomanga akuphatikizapo HEC, HPMC, CMC, PAC, MHEC, etc.
Nonionic water-soluble cellulose ethers ndi zothandiza zomangira zomangira chifukwa cha zomwe zimamangiriza, kukhazikika kwa kubalalitsidwa, komanso kuthekera kosunga madzi. HPMC, MC kapena EHEC ntchito ambiri simenti ofotokoza kapena gypsum yomanga, monga zomangamanga matope, simenti matope, ❖ kuyanika simenti, gypsum, cementitious osakaniza ndi emulsion putty, etc., amene kumapangitsanso kupezeka kwa simenti kapena mchenga ndi bwino kwambiri. zomatira , zomwe ndizofunikira kwambiri pa pulasitala, simenti ya matailosi ndi putty. Kwa simenti, HEC sikuti ndi retarder, komanso wothandizira madzi. HEHPC ilinso ndi cholinga ichi. Ma cellulose ethers nthawi zambiri amagwiritsidwa ntchito limodzi ndi ma gluconate mumatope monga zowonjezera zowonjezera zowonjezera. MC kapena HEC ndi CMC nthawi zambiri amagwiritsidwa ntchito ngati gawo lolimba la wallpaper. Ma cellulose ethers apakati kapena apamwamba kwambiri amagwiritsidwa ntchito kwambiri pazomatira pazithunzi ndi zida zomangira.
Hydroxypropyl methylcellulose HPMC mankhwala amaphatikiza katundu wambiri wakuthupi ndi mankhwala kuti akhale chinthu chapadera chogwiritsa ntchito kangapo. Makhalidwe osiyanasiyana ndi awa:
(1) Kusunga madzi: Imatha kusunga chinyontho pamabowo monga matabwa a simenti ndi njerwa.
(2) Mafilimu opangira mafilimu: Ikhoza kupanga filimu yowonekera, yolimba, yofewa yokhala ndi mafuta abwino kwambiri.
(3) Organic solubility: Izi zimasungunuka mu zosungunulira zina organic, monga Mowa/madzi, propanol/madzi, dichloroethane ndi zosungunulira dongosolo wopangidwa ndi zosungunulira awiri organic mu milingo yoyenera.
(4) Thermal gelation: Pamene njira yamadzimadzi ya mankhwalawa ikatenthedwa, imapanga gel osakaniza ndikusintha kukhala yankho pambuyo pozizira.
(5) Zochita zapamtunda: Perekani zochitika zapamtunda mu yankho kuti mukwaniritse bwino emulsification ya colloidal ndi chitetezo, komanso kukhazikika kwa gawo.
(6) Kuyimitsidwa wothandizira: Hydroxypropyl methylcellulose imatha kuteteza tinthu tating'onoting'ono kuti tisakhazikike, potero kulepheretsa mapangidwe a mpweya.
(7) Colloid yoteteza: Itha kuletsa madontho ndi tinthu ting'onoting'ono kuti tisagwirizane kapena kukhazikika.
(8) Kumamatira: Kumagwiritsidwa ntchito ngati chomangira cha inki, zinthu za fodya, ndi zopangidwa ndi mapepala, kumakhala ndi ntchito zabwino kwambiri.
(9) Kusungunuka kwamadzi: Izi zitha kusungunuka m'madzi mosiyanasiyana, ndipo ndende yake yayikulu imangokhala ndi kukhuthala.
(10) Nonionic inertness: Mankhwalawa ndi nonionic cellulose ether ndipo samaphatikizana ndi mchere wachitsulo kapena ma ion ena kuti apange mpweya wosasungunuka.
(11) Kukhazikika kwa acid-base: koyenera kugwiritsidwa ntchito mkati mwa pH ya 3.0-11.0.
(12) Zosakoma komanso zopanda fungo, zosakhudzidwa ndi metabolism; amagwiritsidwa ntchito ngati zowonjezera muzakudya ndi mankhwala, samapangidwa ndi metabolism muzakudya ndipo sapereka zopatsa mphamvu.
Chifukwa chake, hydroxypropyl methylcellulose HPMC ili ndi malo ofunikira pantchito yomanga, ndipo cellulose yobiriwira idzagwiritsidwa ntchito kwambiri pantchito yomanga. Ubwino wapamwamba, mitengo yabwino komanso ntchito zabwinoko ndizomwe opanga ma cellulose athu ndi latex powder amatsata nthawi zonse. Future Day imatsatira malingaliro abizinesi a "kupulumuka mwaubwino, chitukuko cha sayansi ndi ukadaulo, msika ndi mbiri, komanso magwiridwe antchito ndi kasamalidwe". Hydroxypropyl methylcellulose wathu, redispersible latex powder, ndi hydroxyethyl cellulose amapereka mankhwala apamwamba kwambiri kwa makasitomala ambiri.
