5, eyona njongo iphambili
Ibakala Industrial HPMC isetyenziswa ikakhulu njenge dispersant kwimveliso yepolyvinyl chloride, kwaye yeyona arhente encedisayo ekulungiseleleni PVC ngokunqunyanyiswa polymerization. Ukongeza, inokusetyenziswa njenge-thickener, i-stabilizer, i-emulsifier, i-excipient, kunye ne-ejenti yokugcina amanzi kwimveliso yezinye ii-petrochemicals, iingubo, izinto zokwakha, izisusa zepeyinti, iikhemikhali zezolimo, ii-inki, ukuprintwa kwe-textile kunye nokudaya, i-ceramics, iphepha. , izithambiso, njl., i-agent yokwenza ifilimu, njl. Ukusetyenziswa kwii-resin zokwenziwa kunokwenza iimveliso ezifunyenweyo zibe neempawu zamasuntswana aqhelekileyo kunye akhululekileyo, ubunzima obuthile obufanelekileyo kunye nokusebenza okugqwesileyo kokucubungula, ngaloo ndlela ngokusisiseko kuthatha indawo ye-gelatin kunye ne-polyvinyl alcohol njenge-dispersants.
Iindlela ezintandathu zokuphelisa:
(1). Thatha umlinganiselo ofunekayo wamanzi ashushu, uyibeke kwisitya kwaye uyifudumeze ukuya kuma-80 ° C, kwaye ngokuthe ngcembe wongeze le mveliso phantsi kokuvuselela kancinane. I-cellulose idada kumphezulu wamanzi ekuqaleni, kodwa ngokuthe ngcembe isasazwa ukwenza udaka olufanayo. Isisombululo sapholiswa ngelixa sishukumisa.
(2). Ngaphandle koko, fudumeza i-1/3 okanye i-2/3 yamanzi ashushu ukuya ngaphezu kwe-85 ° C, yongeza i-cellulose ukuze ufumane i-slurry yamanzi ashushu, uze udibanise inani eliseleyo lamanzi abandayo, qhubeka uvuselela, kwaye upholise umxube obangelwayo.
(3). Umnatha weselulosi ulungile ngokwentelekiso, kwaye ukho njengamasuntswana amancinci kumgubo oxutywe ngokulinganayo, kwaye unyibilika ngokukhawuleza xa udibana namanzi ukwenza i-viscosity efunekayo.
(4). Kancinci kwaye ngokulinganayo yongeza i-cellulose kwiqondo lokushisa, uqhube ngokuqhubekayo de kube isisombululo esicacileyo senziwe.
