Kuyaziwa ukuba ukwakhiwa kwe-insulation yangaphandle eludongeni ebusika kufuna ukulungiswa okukhethekileyo kunye nokuqwalaselwa.Ngokubhekiselele kwizinto ezisetyenziselwa ukwakhiwa, i-hydroxypropyl methylcellulose (i-HPMC) yinto esebenzayo esetyenziswe ngokubanzi kwishishini lokwakha ngenxa yeempawu zayo ezintle kunye neempawu.
I-HPMC yi-non-toxic, ivumba, umgubo omhlophe onokuchithwa ngokukhawuleza emanzini ukwenza ulwelo lwe-viscous ebonakalayo.Isoloko isetyenziswa njengesibophelelo esibalulekileyo ekwakhiweni kodaka oluxutywe ngodaka.Inokuphucula ukubambelela kodaka kunye namandla ezinto zokwakha.Ukongeza, i-HPMC ikwasetyenziswa njengesizinzisi kunye nesityebi kwiimveliso zegypsum zokwakha, ezifana neecaulks, iiputty powders, kunye nezinto zokuhombisa.
Kulwakhiwo lokugquma eludongeni lwangaphandle, i-HPMC ingasetyenziswa njengenxalenye ebalulekileyo yodaka lwebhondi kwizixhobo zokugquma ibhondi, iibhodi zogwebu kunye neendonga kunye.Ngokubanzi, inkqubo yokwakha ibandakanya ukusebenzisa udaka oludibeneyo kumphezulu wodonga lwangaphandle kunye nokufaka i-insulation kuyo.Ukongeza, umphezulu ugqunywe nge-mesh kunye ne-topcoat ukwenzela ukhuseleko oluphezulu.Iinzuzo zokusebenzisa i-HPMC ngexesha lokwakha zichazwe ngezantsi:
1. Ukwandisa ukunamathela.
Enye yeenzuzo eziphawulekayo zokusebenzisa i-HPMC kukukwazi ukuphucula ukunamathela.Ukwakheka okukodwa kwe-HPMC kuyinceda yenze iqhina eliqinileyo phakathi kodaka kunye nokugquma.Oku kuthetha ukuba umgangatho wokwakha uya kuphucuka, ekugqibeleni ukhokelele kwiinkqubo zokugquma ezithembekileyo kwizakhiwo.
2. Ukuphucula ukusebenza.
Enye inzuzo yokusebenzisa i-HPMC ngexesha lokwakha kukuba iphucula ukusebenza kodaka.Ukusebenziseka kubhekiselele kubuchule bokwakha kunye nokusebenza kodaka.Ngokwenza umxube lula kwaye ulwelo ngakumbi, HPMC iphucula processability of ancamathele.
3. Ukugcinwa kwamanzi okwandisiweyo.
Kwimozulu ebandayo, ukufuma kodaka kukhawuleza kuphuphe.Ngoko ke, enye yeengxaki eziphambili ekwakhiweni kwe-insulation yangaphandle eludongeni ebusika kukuqinisekisa ukuba udaka luhlala lunokwakhiwa kunye neebhondi ngokufanelekileyo.I-HPMC inceda ukulawula ukufuma kodaka, ngaloo ndlela inceda ukugcina ukusebenza kwayo.Oku kuqinisekisa ukuba udaka luhlala luluncedo kuyo yonke inkqubo yokwakha.
4. Ukuphucula umgangatho jikelele.
Ngokuphucula ukubambelela, ukusebenza kunye nokugcinwa kwamanzi, i-HPMC inceda ekuqinisekiseni umgangatho opheleleyo weenkqubo zokugquma iindonga zangaphandle.Ukusetyenziswa kwayo ngexesha lokwakha kunokukhokelela kwimveliso yokuphela engcono, okwenza iinkqubo zokugquma zithembeke ngakumbi kwaye zihlala zihlala njalo.
Inokubonwa ukuba i-HPMC idlala indima ebalulekileyo ekwakhiweni kwe-insulation yangaphandle eludongeni ebusika.Iimpawu zayo ezizodwa zenza kube yinto efanelekileyo yokuphucula umgangatho kunye nokusebenza kakuhle kwenkqubo yokwakha.
Ukusetyenziswa kwe-HPMC kulwakhiwo lwe-insulation eludongeni lwangaphandle luphuhliso oluhle olunokuphucula umgangatho uwonke wokwakhiwa kwendawo.Inokubonelela nge-insulation engcono, ukuqina kunye nokusebenza kakuhle kwamandla kumakhaya kunye nezakhiwo zorhwebo.Njengoko ishishini lokwakha liqhubeka nokuphuhlisa kwaye likhula, ukusetyenziswa kwe-HPMC ngokungathandabuzekiyo kuya kudlala indima ebalulekileyo ekuboneleleni ngezisombululo ezizinzileyo nezomeleleyo kwimo engqongileyo eyakhiweyo.
