Mmekọrịta dị n'etiti HPMC na tile grout

1. Okwu Mmalite nke Hydroxypropyl Methylcellulose (HPMC)

Hydroxypropyl Methylcellulose (HPMC)bụ cellulose ether na-abụghị ionic nke a na-ejikarị eme ihe owuwu ụlọ, ọgwụ, nri, kemịkalụ kwa ụbọchị na ụlọ ọrụ ndị ọzọ. A na-eme ya site na ihe polymer eke sitere na mgbanwe kemịkalụ ma nwee ezigbo mmiri solubility, njupụta, njigide mmiri, imepụta ihe nkiri na nkwụsi ike nkwusioru. N'ihe gbasara ihe owuwu ụlọ, a na-ejikarị HPMC eme ihe na ngwa ngwa akọrọ, nrapado tile, putty powder, grout, wdg iji melite arụmọrụ ụlọ ma welie àgwà nke ngwaahịa ikpeazụ.

2. Ọrụ na nhazi nke tile grout

Tile grout bụ ihe eji emeju oghere dị n'etiti taịl nile, nke nwere ọrụ nke ịkwalite ihe ịchọ mma, mgbochi mmiri, mgbochi mildew na nkwụsị mgbape. Ihe ndị bụ isi nke grout gụnyere:
Simenti ma ọ bụ resin: dị ka isi ihe njikọ, na-enye ike na ike;
Ihe eji eme ihe: dị ka ájá quartz, calcium carbonate, wdg, na-eme ka ọ dịkwuo mma nkwụsi ike na nkwụsi ike nke grout;
Ihe mgbakwunye: dị ka HPMC, latex ntụ ntụ, pigmenti, wdg, nke na-enye grout arụ ọrụ ihe owuwu dị mma, njigide mmiri, nkwụsi ike na ịdịte aka.

3. Ọrụ HPMC na tile grout

Agbanyeghị na ọnụọgụ HPMC agbakwunyere na grout tile dị ntakịrị, ọrụ ya dị oke mkpa, na-egosipụtakarị n'akụkụ ndị a:

(1) Njide mmiri

HPMC nwere ezigbo njide mmiri. Na grout, ọ nwere ike na-egbu oge evaporation mmiri, melite hydration arụmọrụ nke ciment, zuru ezu hydrate ciment, na-eme ka adhesion na ike nke grout, na ibelata cracking na powdering mere site ngwa ngwa mfu mmiri.

(2) Melite ịrụ ọrụ ihe owuwu

HPMC nwere ike ime ka rheology nke grout dịkwuo mma, mee ka slurry dị mfe ịkwanye na itinye, meziwanye ịdị nro nke ihe owuwu, ma zere nsogbu ndị dị ka agglomeration na sagging n'oge a na-ewu ụlọ. Tụkwasị na nke ahụ, ọ nwere ike ịgbatị oge ihe owuwu ahụ, na-enye ndị ọrụ ohere ka ha gbanwee ma melite ogo ụlọ.

(3) Gbochie mgbawa na mbelata

Akpụkpọ anụ ahụ na-adịkarị mfe ịkụda na mgbawa n'ihi na-ekpochapụ ngwa ngwa nke mmiri n'oge usoro siri ike. Mmetụta njide mmiri nke HPMC nwere ike belata ihe ize ndụ a nke ọma, nọgide na-enwe nkwụsi ike nhazi nke grout, belata ọgbọ nke microcracks, ma melite mmetụta grouting.

(4) Kwalite ihe onwunwe na-egbochi sagging

N'oge a na-arụ ụlọ kwụ ọtọ (dị ka mgbidi mgbidi), onye na-ahụ maka ihe na-eme ka ọ na-adaba na-adaba ma ọ bụ na-ada mbà n'ihi ike ndọda. HPMC na-edozi rheological Njirimara nke caulking gị n'ụlọnga na mma ya thixotropy, nke mere na ọ na-ejigide a elu viscosity na a static steeti, na-eweghachi fluidity n'oge edemede ma ọ bụ na-ewu ọrụ, si otú ibelata sag nsogbu na-emeziwanye ewu arụmọrụ.

(5) Melite nguzogide ntu oyi na nguzogide ihu igwe

HPMC nwere ike imeziwanye ikike onye na-ahụ maka ihe na-eme ka ọ ghara iguzogide ikuku na-agbaze na okirikiri, nke mere na ọ na-anọgide na-akwụsi ike na gburugburu ebe okpomọkụ dị ala ma ọ naghị adị mfe ntụ ntụ ma ọ bụ daa. N'otu oge ahụ, ọ nwekwara ike ịkwalite nguzogide ihu igwe nke onye na-ahụ maka caulking, nke mere na ọ ka nwere ike ịnọgide na-arụ ọrụ nke ọma n'okpuru ọnọdụ siri ike dị ka iru mmiri na radieshon ultraviolet, na ịgbatị ndụ ọrụ ya.

4. Ihe ndị na-emetụta arụmọrụ nke HPMC

Oke dị ka molekụla molekụla HPMC, ogo nnọchi anya, na viscosity ga-emetụta arụmọrụ ikpeazụ nke onye na-ahụ maka caulking. N'ikwu okwu n'ozuzu:
HPMC viscosity dị elu nwere ike inye nkwụsi ike siri ike na njigide mmiri, mana ọ nwere ike ibelata mmiri mmiri;
Ogo kwesịrị ekwesị nke nnọchi (methoxy na hydroxypropyl ọdịnaya) nwere ike melite solubility ma hụ na ịdị n'otu nke onye na-ahụ maka caulking;
Usoro onunu kwesiri ekwesi nwere ike buliri ikike na ogologo oge nke onye na-eme ihe nleba anya, mana oke onunu ogwu nwere ike ibute oke viscosity, na-emetụta ihe owuwu na mmepe ike.

Dị ka isi ihe mgbakwunye na tile caulking agents,HPMCtumadi na-eme ka ogo nke ihe na-eme ka ọ dịkwuo mma site na ime ka njide mmiri dịkwuo mma, melite arụmọrụ ihe owuwu, na ịkwalite nkwụsị nke nkwụsị na ịdịte aka. Nhọrọ ezi uche dị na ya nke ụdị HPMC dị iche iche na usoro onunu ogwu nwere ike ịkwalite arụmọrụ nke ndị na-emepụta ihe, hụ na a na-ewu ụlọ nke ọma, ma welie mmetụta ịchọ mma na nchebe ikpeazụ. Ya mere, na nhazi nhazi nke ndị na-ahụ maka tile caulking, nhọrọ na ngwa nke HPMC dị oke mkpa.
