Iyini i-HPMC kudaka lwengxube eyomile?

IHydroxypropyl methylcellulose (HPMC) iyisithako esiyinhloko ekwakhiweni kodaka lwengxube eyomile futhi idlala indima ebalulekile ekuthuthukiseni izici ezihlukahlukene zodaka. I-dry mix mortar iyingxube exutshwe ngaphambili ye-aggregate ecolekile, usimende nezithasiselo ezidinga kuphela ukungezwa ngamanzi endaweni yokwakha. Kulokhu, i-HPMC isebenza njengesengezo esisebenza ngezindlela eziningi esiza ukuthuthukisa ukusebenza nokusebenza kodaka.

Isakhiwo samakhemikhali kanye nezakhiwo:

I-HPMC i-semi-synthetic polymer etholakala ku-cellulose, i-polymer yemvelo etholakala ezindongeni zamaseli ezitshalo. Ngochungechunge lokuguqulwa kwamakhemikhali, amaqembu e-hydroxypropyl kanye ne-methyl angeniswa kumgogodla we-cellulose ukuze akhe i-HPMC. Lokhu kuguqulwa kunikeza i-HPMC izakhiwo ezihlukile, iyenze inyibilike emanzini futhi iyenze ibe ukuqina, ukunamathela, kanye namakhono okwenza ifilimu.

Imisebenzi ye-dry mix mortar:

Ukugcinwa kwamanzi:

I-HPMC ithuthukisa ukugcinwa kwamanzi kodaka lwengxube eyomile, ivimbele ukuhwamuka kwamanzi ngokushesha futhi iqinisekise ukugeleza okufanele kukasimende. Lokhu kubalulekile ekuthuthukiseni amandla nokuqina kodaka.

Ukuqina:

Ngenxa yokuqina kwayo, i-HPMC inyusa ukungaguquguquki nokusebenza kodaka, ikwenze kube lula ukuyisebenzisa futhi ibe nokusebenza okungcono ngesikhathi sokwakha.

Thuthukisa ukunamathela:

I-HPMC isebenza njengesibophezelo ukukhuthaza ukunamathela okungcono kodaka kuma-substrates ahlukahlukene. Lokhu kubalulekile ukuze kuhlanganiswe ngempumelelo udaka endaweni efakwe kuyo.

Yehlisa ukuwohloka:

Ukwengeza i-HPMC kusiza ukunciphisa ukuwohloka noma ukuwohloka kodaka, ikakhulukazi ezinhlelweni eziqondile. Lokhu kunomthelela ekuzinzeni nasekufaneni kodaka olusetshenzisiwe.

Setha ukulawula isikhathi:

I-HPMC ithinta isikhathi sokumiswa kodaka. Ngokulungisa ngokucophelela umthamo, ukusetha isikhathi kungalawulwa ukuze kuhlangatshezwane nezidingo ezithile zephrojekthi.

Thuthukisa ukuguquguquka:

Ukuba khona kwe-HPMC kusiza ukwandisa ukuguquguquka kodaka futhi kunciphisa amathuba okuqhekeka. Lokhu kubaluleke kakhulu lapho i-substrate ingase inyakaze kancane.

Ukuqhubekela phambili okuthuthukisiwe:

Ukusebenza kokwakha kuyisici esibalulekile ezintweni zokwakha. I-HPMC ithuthukisa ukusebenza okuphelele kodaka lwengxube eyomile, okwenza kube lula ukuliphatha nokulisebenzisa.

Imelana nokuntengantenga nokuwa:

I-HPMC inikeza i-mortar thixotropy, okusho ukuthi lapho inyakaziswa noma isetshenziswa ngamandla, i-viscosity yayo iyancipha, okwenza kube lula ukusabalala, futhi ibuyele esimweni esibucayi kakhulu lapho uphumule, ukuvimbela ukugoqa noma ukuwa.

Izindawo zokufaka isicelo:

I-HPMC isetshenziswa kabanzi ezinhlobonhlobo zezicelo zodaka ezomile ezihlanganisa:

I-tile glue
Ukukhipha kanye ne-plaster
i-self-leveling compound
I-Caulk
udaka lwamatshe
I-EIFS (Ingaphandle Le-Wall Insulation kanye ne-Finishing System)

IHydroxypropyl methylcellulose iyisengezo esisebenza ngezindlela eziningi futhi esibalulekile ekwakhekeni kodaka lwengxube eyomile. Izici zayo eziyingqayizivele zisiza ukuthuthukisa ukugcinwa kwamanzi, ukusebenza kahle, ukunamathela kanye nokusebenza okuphelele kodaka. Njengoba izinqubo zokwakha ziqhubeka nokuvela, indima ye-HPMC ekuthuthukiseni ikhwalithi nokusebenza kahle kwezicelo zodaka lwengxube eyomile kungenzeka ihlale ibalulekile.
