Putty anonzwa kuremerwa
Panguva yekuvakwa kweputty, vamwe vanhu vachasangana nemamiriro ezvinhu kuti ruoko runonzwa runorema. Ndechipi chikonzero chaicho? Inogona kuvandudzwa sei?
Zvikonzero zvinowanzoita kuti putty anzwe kurema ndeaya:
1. Kusashandiswa kwakashata kweiyo viscosity modhi ye cellulose ether:
Muchiitiko ichi, viscosity ye cellulose ether inowanzove yakakwirira kwazvo, uye putty yakagadzirwa ichanzwa inorema panguva yekutsvaira;
Chimwe chikonzero ndechekuti panguva yekuvaka muzhizha, kushandiswa kwehydroxypropyl methylcellulose ether ine urombo husina kusimba hwekushisa kunogona kuita kuti putty irasikirwe neviscosity, izvo zvinokanganisa kuvaka kunzwa.
2. Chisizvo chiyero kana hupfu hwehupfu:
Kazhinji, kune zvakawanda zvakawandisa inorganic gelling materials, kana kutsetseka kwechizadziso chakasarudzwa chakanyanya kunaka, icho chinowanzonamatira kune banga;
Izvo zvakare zvinogoneka kuti kuderedza mutengo, hapana kana zvishoma zvinowedzera zvekuvandudza ruoko kunzwa zvinowedzerwa, senge starch ethers uye thixotropic lubricant.
Nzira dzekuvandudza 1
Yakakodzera mbishi zvinhu reshiyo uye fineness kusarudzwa
Iko kunaka kweiyo yakazara mbishi zvinhu inogona kudzorwa pa150-200 mesh, uye kunaka kwekuzadza kunogona kazhinji kuve 325 mesh, kwete yakanyanya kunaka;
Huwandu hwehupfu hwepolyvinyl doro haifaniri kudarika 6%;
Izvo zvinodiwawo kudzidza kudzikisira huwandu hweinorganic cementitious zvinhu. Kazhinji, zvakakwana kudzora simenti pa 28% -32%, uye shandisa additives kuti iwedzere kushanda kwayo.
Kuvandudza nzira 2
Sarudza iyo chaiyo cellulose ether
Kazhinji, tinokurudzira hydroxyethyl methyl cellulose ether nekushanda kuri nani, iyo ine zviri nani kupisa kwekushisa kwepamusoro uye inogona kunyatsogadziriswa kukuvaka kwezhizha uye kuderedza mari yekuchinja kwechando uye yezhizha;
Chinokosha ndechokusarudza cellulose ether ine viscosity yakakodzera. Kazhinji, cellulose ether ine viscosity ye80,000 kusvika 100,000 inokwana putty powder, asi huwandu hweselulosi ether hunowedzerwa hunofanira kutariswa kuburikidza nekuyedza kuvaka kwakanaka!
Nzira dzekuvandudza 3
Wedzera zvinowedzera kuti uvandudze kunzwa kwemaoko
Pakupedzisira, tinogona kufunga kuwedzera starch ether kana thixotropic lubricant (bentonite) kuvandudza kunzwa kwedhaka;
Rangarira: kusanganiswa kwesainzi formula ndiyo kiyi yekugadzirisa dambudziko!
