I-4. Ukuphucula amandla
I-HPMC inokuphucula ububi phakathi kokuthambeka kunye nokuphucula amandla kwaye kuphuculwe amandla okuxhuzula ngokunamathela ngokwenza iyunifomu kunye ne-faker ye-faces egudileyo. Oku kubaluleke kakhulu kukuzinza kwezakhiwo zolwakhiwo ezinje ngeendonga kunye nemigangatho, kwaye unokuthintela ngokufanelekileyo iithayile, ujonge iithayile, njl njl.
I-5. Ukuntywila kwe-anti-slip
Kwizicelo ezinjenge-tilestheives, i-HPMC inokuphucula ubuchule bokwenza izinto ze-anti-slip. Oku kunceda ukugcina iithayile zilungiselelwe indawo yokwakha ethe nkqo, ukunciphisa irejista yohlengahlengiso kunye nomthwalo, kwaye ke kuphucule umgangatho wokwakha.
(3) Izicelo ezithile ze-HPMC kwisakhiwo esahlukileyo sokwakha
I-1. I-Tile Adhesive
ETile Adhesive, i-HPMC ayidlala kuphela indima ekuthandeni nasekugcinweni kwamanzi, kodwa iphucula ukusebenza kwe-anti-slip ye-tile ye-tile ye-tile, iqinisekisa uzinzo lweethayile ngexesha lolwakhiwo. Iipropathi zayo ezahlukileyo ze-ratheology zenza ukuba ukunamathela ukugcina uVetvisity ofanelekileyo phantsi kweemeko ezahlukeneyo zokwakha, kwenza kube lula ukutshintsha nokwakha.
I-2. Udonga
I-HPMC ikakhulu idlala indima yokugcina amanzi kunye nokutsala ngaseludongeni, ukwenza i-putty isebenze ngakumbi kwaye inomgangatho ogudileyo emva komile. Ukugcinwa kwayo kwamanzi kunokunciphisa ukuqhekeka kunye nokuntywila komaleko wokubeka ngexesha lokwakha, kunye nokuphucula umgangatho wokuhamba okokugqibela.
I-3. Udaka Olowomileyo
Kuludaka owomileyo, owona msebenzi uphambili we-HPMC kukugcina umswakama kwaye uthintele ukuphulukana kwamanzi, ngaloo ndlela ukuphucula ukusebenza kunye nokunamathela kodaka. Inokuhlengahlengisa ukungqinelana kodaka ukuba ilungele iimeko zokwakha ezahlukileyo, ezinjengokulala kaMatshi, udaka lwe-STTAR.
4. Ukwakha itywirha
I-HPMC isetyenziswa ikakhulu ekwakheni i-wialants yokuphucula ulwelo kunye nokusebenza kwe-colloid, ukuze ikwazi ukugcwalisa ngokulinganayo ngexesha lokufaka isicelo kunye nokunamathela okulungileyo kunye nokunamathela. Ukugcinwa kwayo kwamanzi kungathintela itywina lokuphulukana namanzi ngokukhawuleza kwaye kuphucule umgangatho wokwakha.
