Iyini indima ye-HPMC eguquliwe ekwakheni udaka?

I-Hydroxypropyl Methylcellulose eguquliwe (i-HPMC eguquliwe)iyisengezo esibalulekile se-polymer ezintweni zokwakha, ikakhulukazi ezinhlelweni zokwakha udaka. Ithuthukisa kakhulu ukusebenza kwe-HPMC ngezindlela ezibonakalayo noma zamakhemikhali, ukuze ikwazi ukunikeza ukusebenza okungcono kokwakha, ukugcinwa kwamanzi, izakhiwo zokulwa nokuwa kanye nokubopha kumaphrojekthi okwakha.

1. Indlela yokusebenza kwe-HPMC eguquliwe

I-HPMC eguquliwe iyi-non-ionic cellulose ether. Izinzile endaweni ene-alkaline futhi inokuncibilika okuhle nokuhlakazeka ngokufakwa esikhundleni kwamaqembu e-hydroxypropyl kanye ne-methyl ku-skeleton ye-cellulose. Ukwelashwa kokuguqulwa kuvame ukufaka:

Ukwelashwa kwendawo (isibonelo: ukusabela kwe-etherification, ukuthuthukisa ukuncibilika noma ukuhlakazeka okusheshayo);

Ukusabela kokuxhumanisa (ukuthuthukisa ukuhambisana nokugcinwa kwamanzi);

Ukuguqulwa kwe-hydrophobic (ukuthuthukisa ukumelana nokuwa kanye nokumelana namanzi);

Ukwelashwa kokusabela kokushisa (ukulawula izinga lokushisa lejeli ukuze kuhlangatshezwane nezidingo zokwakha), njll.

Ngalezi zindlela zokuguqula, i-HPMC kulula ukuyihlakaza ku-mortar ukuze yakhe isixazululo esifanayo se-colloidal, esingalungisa ngempumelelo izakhiwo ze-rheological, ukugcinwa kwamanzi kanye nezakhiwo zokulwa nokuwa kwe-mortar.

2. Indima eyinhloko ye-HPMC eguquliwe ekwakheni udaka

2.1. Ukuthuthukisa ukugcinwa kwamanzi

I-HPMC eguquliwe yakha isakhiwo senethiwekhi esinezinhlangothi ezintathu ku-mortar, ivimbela ngempumelelo ukulahleka kwamanzi. Lesi sici sibaluleke kakhulu enqubweni yokufuthwa kwe-samente, engaqinisekisa ukuthi i-samente ifuthwa ngokugcwele, inciphise ingozi yokuncibilika nokuqhekeka, futhi ithuthukise amandla ayo kamuva. Ibaluleke kakhulu ekwakheni ezindaweni ezinokushisa okuphezulu nezomile.

2.2. Thuthukisa ukusebenza kokwakha

I-HPMC eguquliwe inemiphumela emihle kakhulu yokuthambisa kanye nokuqina, okwenza kube lula ukufaka nokuklwebha uthayela ngemva kokuxuba, kunciphisa ukumelana kwamathuluzi okwakha kanye nokuthuthukisa ukusebenza kahle kokwakha. Ifaneleka kakhulu uthayela wokufutha ngomshini, ithuthukisa ukumpompa kanye nokulawula.

2.3. Thuthukisa ukusebenza kokulwa nokuwa

Ukusebenza okulwa nokugoba kubalulekile ezinhlelweni zokwakha i-facade njengezinamathiseli zethayela kanye nezimbobo ze-plaster. I-HPMC eguquliwe ingathuthukisa i-viscosity kanye ne-thixotropy, ukuze imbobo ibe nokuvumelana okuhle esimweni esingaguquki, igweme ukushelela ngemva kokusetshenziswa, futhi iqinisekise ikhwalithi yokwakha.

2.4. Thuthukisa ukunamathelana nokuhlangana

I-HPMC eguquliwe ingathuthukisa ukunamathelana phakathi kwe-mortar nezinto ezifana nesisekelo namathayili. Izakhiwo zayo zokwakha ifilimu ziyenza ikwazi ukwakha ungqimba lwefilimu oluguquguqukayo ebusweni be-mortar, okuthuthukisa amandla okubopha phakathi kwe-interfacial. Ngesikhathi esifanayo, ithuthukisa ukuhlangana okuphelele kwe-mortar ukuvimbela ukuqhekeka nokuqhekeka.

2.5. Lungisa ukuhambisana kanye nokugeleza

Izinqubo zokwakha ezahlukene zinezidingo ezahlukene zokuvumelana kwe-mortar. I-HPMC eguquliwe ine-thixotropy ethile, evumela i-mortar ukuthi igcine ukugeleza okuhle ngaphansi kokucindezeleka futhi ibuyisele ngokushesha ukufana lapho imile, ihlangabezana nezidingo zokwakha ezahlukene njengokuplasta, ukulevelisha, kanye nokufaka i-caulking.

3. Ukusetshenziswa okuqondile kuma-mortar okwakha ahlukene

3.1. Udaka olunamathelayo lwethayela

I-HPMC eguquliwe ingathuthukisa ukungasheleli nokugcinwa kwamanzi kwezinamathiseli zamathayili futhi ithuthukise ikhono lokunamathela kwamathayili amakhulu. Ikakhulukazi ekwakhiweni okunamathela kancane, iqinisekisa ukuthi ukwakhiwa kulula futhi kuqine ukunamathela.

3.2. Ukuplasta udaka

Ku-plastered mortar, i-HPMC eguquliwe ithuthukisa ukusebenza kahle, inciphisa izinkinga zokugoba nokuqhekeka okubangelwa ukuhwamuka kwamanzi ngokushesha, futhi iqinisekisa indawo ebushelelezi nethambile. Ifanele futhi i-mortar yokufutha ngomshini ukuze kuthuthukiswe ukusebenza kahle kokupompa.

3.3. Udaka oluphansi kanye nodaka oluzilinganisayo

Ukuzilinganisa kunezidingo eziphezulu zokugeleza kwamanzi. I-HPMC eguquliwe inikeza ukugeleza okufanele ngaphandle kokulahlekelwa amandla, ngenkathi ilawula ukuhlukaniswa kwamanzi futhi ithuthukisa ikhwalithi yobuso kanye nokuba yisicaba ngemva kokubekwa.

3.4. Lungisa udaka

Uma kulungiswa imifantu emincane kanye nokulungiswa kwezingqimba ezincane, i-HPMC eguquliwe ingathuthukisa amandla okubopha phakathi kwengqimba ye-mortar ne-base, inciphise ingozi yokuhlukanisa kanye nokupholisha i-powder esigabeni esilandelayo, futhi ifanele ukwakhiwa okuningiliziwe kwezindonga, amabhuloho, njll.

4. Izincomo zokukhetha kanye nomthamo we-HPMC oguquliwe

Kumafomula angempela, inani le-HPMC eguquliwe engeziwe ngokuvamile lingu-0.2% ~ 0.6% (ngokusekelwe esisindweni esiphelele sempuphu eyomile), futhi inani elithile lidinga ukunqunywa ngokuya ngohlobo lwe-mortar, indawo yokwakha kanye nezidingo zokusebenza.

Izidingo zokugcina amanzi eziphezulu: i-HPMC eguquliwe ekhethiwe enezinga eliphezulu lokufaka esikhundleni kanye nezinhlayiya ezincane;

Ukumelana nokuwa okuphezulu: khetha i-viscosity ephezulu, i-HPMC eguquliwe ye-thixotropic;

Uhlelo lokuzilinganisa noma lwephansi: khetha i-viscosity ephansi, uhlobo lokugeleza okuphezulu oluguquliwe lwe-HPMC;

Izidingo zokuncibilika okusheshayo (udaka oluxutshwe kusengaphambili): khetha i-HPMC elungisiwe ngokushesha ephathwe ubuso.

I-HPMC eguquliwe idlala indima ebalulekile emisebenzini eminingi ekwakheni udaka, ikakhulukazi ekuthuthukiseni ukugcinwa kwamanzi, ukusebenza kokwakhiwa, ukunamathela kanye nokusebenza kokulwa nokuwa. Akugcini nje ngokuthuthukisa izakhiwo zemishini kanye nemiphumela yokwakha ye-mortar, kodwa futhi kunikeza isisekelo esiqinile sezinto zobuchwepheshe besimanje bokwakha (njengokufafaza ngomshini, ukwakhiwa kwefilimu encane, kanye nokubeka i-self-leveling paving). Esikhathini esizayo, ngokuthuthukiswa kwezinto zokwakha eziluhlaza kanye nezinto zokwakha ezisebenza kahle kakhulu, ukusetshenziswa kwe-HPMC eguquliwe emkhakheni we-mortar yokwakha kuzoba kubanzi futhi kuphumelele.
