Ungayenza kanjani i-adhesive yethayela eyomisa ngokushesha nge-HPMC?

Izinamathiselo zamathayela zisetshenziswa kakhulu kumaphrojekthi wokwakha ukuze kuvikeleke amathayela ezindaweni ezingaphezulu njengezindonga naphansi.Inikeza ukunamathela okuqinile phakathi kwe-tile nendawo, ukunciphisa ingozi yokuguquguquka kwe-tile.Ngokuvamile, okunamathelayo kwamathayela kuhlanganisa usimende, isihlabathi, izithasiselo nama-polymers.

I-HPMC (Hydroxypropyl Methyl Cellulose) iyisengezo esibalulekile esingaletha izinzuzo eziningana kuzinto zokunamathisela zamathayili.Ingathuthukisa ukugcinwa komswakama, ukusebenza kahle, ukumelana nokushelela nezinye izici ze-adhesive, futhi ithuthukise amandla ayo okubopha.I-HPMC isetshenziswa kakhulu ezintweni ezinamathelayo zamathayela ngenxa yezindawo zayo ezinhle kakhulu zokugcina amanzi, eziqinisekisa ukuthi ingcina esanda kufakwa ihlala imanzi ukuze kuthuthukiswe ukwakheka okuhle kwebhondi.

Kulesi sihloko, sizoxoxa ngezinyathelo zokwenza i-adhesive yethayela eyomisa ngokushesha nge-HPMC.Kubalulekile ukulandela inqubo efanele ukuze uthole ukuvumelana okufunayo kanye nezakhiwo ze-adhesive.

Isinyathelo 1: Qoqa Izinto Ezidingekayo

Ngaphambi kokuqala inqubo, qiniseka ukuthi unazo zonke izinto ozidingayo ukuze wenze i-adhesive tile.Zihlanganisa:

- HPMC powder

- Portland usimende

- isihlabathi

- amanzi

- isitsha sokuxuba

- ithuluzi lokuhlanganisa

Isinyathelo Sesibili: Lungisa Umkhumbi Wokuxuba

Khetha isitsha sokuxuba esikhulu ngokwanele ukubamba umthamo wezinto ezisetshenziselwa ukwenza ingcina.Qiniseka ukuthi isiqukathi sihlanzekile, somile futhi asinazo izinsalela zokungcola.

Isinyathelo sesi-3: Linganisa Izinto

Kala inani lezinto ezihlukene ngokwezilinganiso ezidingekayo.Ngokuvamile, isilinganiso sokuxuba sikasimende nesihlabathi ngokuvamile singu-1:3.Izithasiselo ezifana ne-HPMC kufanele ziphendule i-1-5% ngesisindo se-samente powder.

Isibonelo, uma usebenzisa:

- 150 amagremu usimende kanye 450 amagremu esihlabathi.

- Uma ucabanga ukuthi uzobe usebenzisa u-2% ngesisindo sempushana kasimende ye-HPMC, uzofaka amagremu angu-3 empushana ye-HPMC

Isinyathelo sesi-4: Hlanganisa usimende nesihlabathi

Faka usimende okaliwe nesihlabathi esitsheni sokuxuba ugovuze kahle kuze kufane.

Isinyathelo sesi-5: Engeza i-HPMC

Ngemuva kokuthi usimende nesihlabathi kuxutshwe, i-HPMC yengezwe emkhunjini wokuxuba.Qiniseka ukuthi uyayikala ngendlela efanele ukuze uthole iphesenti lesisindo oyifunayo.Xuba i-HPMC enhlanganisweni eyomile ize ihlakazwe ngokugcwele.

Isinyathelo sesi-6: Engeza Amanzi

Ngemva kokuxuba ingxube eyomile, qhubeka ufaka amanzi esitsheni sokuxuba.Sebenzisa isilinganiso samanzi-samende esihambisana nohlobo lwe-adhesive ye-tile ohlela ukuyenza.Hamba kancane lapho ungeza amanzi engxubeni.

Isinyathelo sesi-7: Hlanganisa

Hlanganisa amanzi nengxube eyomile futhi uqiniseke ukuthi inokuthungwa okungaguquki.Sebenzisa ukulungiselelwa kwesivinini esiphansi ukuze uthole ukuthungwa okufunayo.Hlanganisa usebenzisa ithuluzi lokuxuba kuze kungabikho izigaxa noma amaphakethe omile.

Isinyathelo sesi-8: Vumela ingcina ihlale

Uma i-adhesive ye-tile isixutshwe kahle, yivumele ihlale imizuzu engaba ngu-10 ngaphambi kokuyisebenzisa.Ngalesi sikhathi, kungcono ukumboza futhi uvale isitsha sokuxuba ukuze okunamathelayo kungomi.

Yilokho kuphela!Manje usunesinamathiselo sethayela esomisa ngokushesha esenziwe nge-HPMC.

Sengiphetha, i-HPMC iyisengezo esibalulekile esingaletha izinzuzo eziningana kuma-adhesive athayela.Ngokulandela izinyathelo ezingenhla, ungakha ngempumelelo i-adhesive yethayela enekhwalithi ephezulu, eyomisa ngokushesha.Ngaso sonke isikhathi qiniseka ukuthi usebenzisa isilinganiso esifanele sezinto zokwakha futhi ukale ngokunembile impushana ye-HPMC ukuze uthole iphesenti lesisindo oyifunayo.Ukwengeza, kubalulekile ukulandela izinqubo ezifanele zokuxuba ukuze uthole ukuthungwa okungaguquki futhi ukwandise ukusebenza kwe-adhesive.
