Khahlanong le khethollo, ntlafatsa ho tšoana ha seretse
E ntlafatsa matla a maqhama a metsi mme e ntlafatsa ho hanyetsa sag.
tsoa moya
Ntlafatsa ts'ebetso ea seretse
Ha viscosity ea cellulose e ntse e phahama 'me ketane ea molek'hule e ntse e le telele, phello ea ho kenya moea e bonahala haholoanyane.
Ho lieha
Synergizes le ho boloka metsi ho lelefatsa nako e bulehileng ea seretse.
Hydroxypropyl starch ether (HPS)
1. Lintho tse phahameng tsa hydroxypropyl ka starch ether li fana ka tsamaiso ka hydrophilicity e tsitsitseng, ho etsa hore metsi a sa lefelloeng a be metsi a tlamiloeng le ho bapala karolo e ntle ea ho boloka metsi.
2. Li-ether tsa starch tse nang le li-hydroxypropyl tse fapaneng li fapana ka bokhoni ba tsona ba ho thusa cellulose ho boloka metsi tlas'a tekanyo e tšoanang.
3. Ho nkela sebaka sa sehlopha sa hydroxypropyl ho eketsa tekanyo ea ho atolosa metsing le ho hatella sebaka sa phallo ea likaroloana, ka tsela eo ho eketsa viscosity le phello e teteaneng.
Thixotropic lubricity
Ho hasana ka potlako ha starch ether tsamaisong ea seretse ho fetola rheology ea seretse 'me e e fa thixotropy.Ha matla a ka ntle a sebelisoa, viscosity ea seretse e tla fokotseha, ho etsa bonnete ba hore ho sebetsa hantle, ho pompa le ho fana ka matla Ha matla a ka ntle a tlosoa, viscosity ea eketseha, e le hore seretse se be le ts'ebetso e ntle ea ho thibela ho fokotseha le ho thibela ho fokotseha. ka phofo ea putty, e na le melemo ea ho ntlafatsa khanya ea oli ea putty, ho benya ho khanya, joalo-joalo.
Phello ea ho boloka metsi a thusang
Ka lebaka la phello ea sehlopha sa hydroxypropyl tsamaisong, starch ether ka boeona e na le litšobotsi tsa hydrophilic.Ha e kopantsoe le selulose kapa e kenngoa ho seretse se itseng, e ka eketsa ho boloka metsi ho isa tekanyong e itseng le ho ntlafatsa nako ea ho omisa holim'a metsi.
Anti-sag le anti-slip
Phello e ntle ea anti-sagging, phello ea sebopeho
Phofo ea latex e ka qhaloang hape
1. Ntlafatsa ho sebetsa ha seretse
Likaroloana tsa phofo ea rabara li qhalakantsoeng tsamaisong, li fa tsamaiso e nang le metsi a mangata, ho ntlafatsa ho sebetsa le ho sebetsa ha seretse.
2. Ntlafatsa matla a tlamo le momahano oa seretse
Ka mor'a hore phofo ea rabara e hasane ka filimi, lintho tse sa tloaelehang le lintho tse phelang tsamaisong ea seretse li kopantsoe hammoho.Ho ka nahanoa hore lehlabathe la samente ka seretse ke skeleton, 'me phofo ea latex e etsa ligament ho eona, e leng ho eketsang momahano le matla.etsa sebopeho se tenyetsehang.
3. Ntlafatsa ho hanyetsa boemo ba leholimo le ho hanyetsa ho qhibiliha ha seretse
Latex phofo ke resin ea thermoplastic e nang le mekhoa e metle ea ho feto-fetoha ha maemo, e ka etsang hore seretse se sebetsane ka katleho le serame se ka ntle le liphetoho tsa mocheso, 'me ka katleho se thibele seretse ho senya ka lebaka la liphetoho tsa mocheso.
4. Ntlafatsa matla a flexural a seretse
Melemo ea polymer le peista sa samente lia tlatsana.Ha mapetsong a hlahisoa ke matla a ka ntle, polymer e ka tšela mapetsong 'me ea thibela mapetsong ho atolosa, e le hore ho thatafala ha fracture le ho senyeha ha seretse ho ntlafatsoe.
