Lisebelisoa:
Sefate sa lebota
- Ho boloka metsi: ho eketsa metsi a mangata ka har'a seretse.
- Anti-sagging: ha o jala corrugation e teteaneng ea jase e ka qojoa.
- Kotulo e eketsehileng ea seretse: ho latela boima ba motsoako o omileng le sebopeho se nepahetseng, HPMC e ka eketsa molumo oa seretse.
Setsi sa Kantle sa Insulation le Finish System ( EIFS )
- Matlafatso e ntlafetseng.
- Bokhoni bo botle ba ho koloba bakeng sa boto ea EPS le substrate.
- Ho fokotsa moea o kenang le ho kenngoa ha metsi.
Boiketsi ba ho iteka
Tšireletso ho tsoa ho metsi le ho senyeha ha lintho tse bonahalang.
Ha ho na phello ho slurry fluidity e nang le viscosity e tlase
HPMC, ha litšobotsi tsa eona tsa ho boloka metsi li ntlafatsa ts'ebetso ea ho qetela holim'a metsi.
Crack Filler
Ho sebetsa hantle: botenya bo nepahetseng le polasetiki.
Ho boloka metsi ho tiisa nako e telele ea mosebetsi.
Sag resistance/ Ketso ya ho hanyetsa: matla a ntlafetseng a ho kopanya seretse.
Likhomaretsi tsa Lithaele
Ho sebetsa ho betere: lubricity le polasetiki ea plaster li netefatsoa, seretse se ka sebelisoa habonolo ebile se potlakile.
Ho boloka metsi hantle: nako e telele ea ho bula e tla etsa hore lithaele li sebetse hantle.
Ho ntlafala ho khomarela le ho hanyetsa ho thella: haholo-holo bakeng sa lithaele tse boima.
Seretse sa motsoako o omileng
Mokhoa o bonolo oa motsoako o omileng ka lebaka la ho qhibiliha ha metsi a batang: sebopeho sa leqeba se ka qojoa habonolo, se loketse lithaele tse boima.
Ho boloka metsi hantle: ho thibela tahlehelo ea mokelikeli ho li-substrates, metsi a loketseng a bolokiloe ka motsoako o tiisang nako e telele ea concreting.
Plaster ea samente
Keketseho ea tlhokeho ea metsi: nako e eketsehileng ea ho bula, sebaka se atolositsoeng sa spry le tlhahiso ea moruo e eketsehileng.
Ho hasana habonolo le ho ntlafatsa ho hanyetsa ho fokotseha ka lebaka la ho tsitsa ho ntlafetseng.
Sephutheloana:
Sehlahisoa sa HPMC se pakiloe ka mokotleng oa pampiri oa mekhahlelo e meraro e nang le mokotla o ka hare oa polyethylene o matlafalitsoeng, boima ba letlooa ke 25kg mokotla ka mong.
Polokelo:
E boloke sebakeng sa polokelo se omeletseng se pholileng, hole le mongobo, letsatsi, mollo, pula.
