Lekwasị anya na cellulose ethers

Kedu ka HPMC si enyere ụlọ aka idobe mmiri?

Hydroxypropyl methylcellulose (HPMC) bụ ihe mgbakwunye dị iche iche a na-ejikarị eme ihe na ihe owuwu, gụnyere ngwaahịa simenti dị ka ngwa agha na plasta, yana tile adhesives na grouts. Ọ bụ ezie na ọ naghị 'edobe' mmiri ozugbo n'ụlọ, ọ na-arụ ọrụ dị mkpa n'ịchịkwa njide mmiri n'ime ihe owuwu ndị a.

Ike njide mmiri: HPMC bụ hydrophilic, nke pụtara na ọ nwere njikọ siri ike maka mmiri. Mgbe agbakwunyere ihe owuwu ihe, ọ na-emepụta ihe nkiri dị mkpa n'akụkụ akụkụ ciment. Ihe nkiri a na-enyere aka ịkụnye mmiri n'ime ihe ahụ, na-egbochi ya ịpụpụ ngwa ngwa n'oge usoro ọgwụgwọ. N'ihi ya, ciment nwere ike ime ka mmiri na-ekpo ọkụ n'ụzọ zuru ezu ma mepụta ike ya, na-eme ka arụmọrụ zuru oke na ịdịte aka nke ihe owuwu ụlọ.

Ịrụ ọrụ: HPMC na-eme ka arụ ọrụ nke ihe owuwu rụọ ọrụ site n'ịkwalite nkwụsi ike ha na ibelata nkwụsịtụ ma ọ bụ slumping. Nke a dị mkpa karịsịa maka ngwa dị ka ngwa agha na plasta, ebe ihe dị mkpa ka ọ dị mfe ịgbasa ma na-ejigide ọdịdị ya na-enweghị oke nrụrụ. Site n'ịchịkwa ọdịnaya mmiri na viscosity nke ngwakọta, HPMC na-ahụ na ihe ahụ na-adị mfe ijikwa ma tinye ya n'ọrụ, na-eme ka ọ dị mma na nhazi.

Mbelata Mbelata: Otu n'ime ihe ịma aka dị na ihe ndị sitere na ciment bụ mbelata n'oge usoro ọgwụgwọ. Mbelata nke ukwuu nwere ike iduga mgbawa na ntụpọ ndị ọzọ, na-emebi iguzosi ike n'ezi ihe nke ụlọ ahụ. HPMC na-enyere aka ibelata mbelata site n'ịkwado ọdịnaya mmiri na-agbanwe agbanwe n'ime ihe niile ahụ, na-enye ya ohere ịgwọ ya nke ọma na-enweghị oke ụda olu. Nke a na-ebute mbelata mbelata mgbawa na mma ogologo oge ịdịte aka nke ụlọ.

Nkwado emelitere: Na taịlị na grouts, HPMC na-eme ka adhesion dịkwuo mma site na imeziwanye ike njikọ dị n'etiti taịlị na mkpụrụ. Ọnụnọ nke HPMC n'ụdị nrapado na-enyere aka ịmepụta njikọ siri ike site n'ịbawanye mpaghara kọntaktị dị n'etiti taịl na mkpụrụ ahụ na ibelata ihe ize ndụ nke nkwụsịtụ ma ọ bụ nkwụsị tile na oge. Nke a dị mkpa iji hụ na iguzosi ike n'ezi ihe na ịdịte aka nke elu tiled n'ime ụlọ, ọkachasị na gburugburu mmiri dị elu dị ka ụlọ ịsa ahụ na kichin.

Mgbanwe mgbanwe: HPMC nwekwara ike inye mgbanwe na ihe owuwu, na-eme ka ha na-eguzogide mgbawa na nrụrụ n'okpuru nrụgide. Nke a bara uru karịsịa maka ngwa ebe a na-emegharị ihe ụlọ ahụ ma ọ bụ ịma jijiji, dị ka ihe na-eme mpụ ma ọ bụ ihe na-ejikọta ọnụ. Site n'ịkwalite mgbanwe na ịdị ike nke ihe ahụ, HPMC na-enyere aka ịnọgide na-eguzosi ike n'ezi ihe nke ụlọ ahụ na ịgbatị ndụ ọrụ ya.

Oge nhazi oge a na-achịkwa: Enwere ike iji HPMC iji chịkwaa oge nhazi nke ihe ndị sitere na ciment, na-enye ohere maka mgbanwe dabere na ihe achọrọ ọrụ na ọnọdụ gburugburu ebe obibi. Site n'ịgbanwe njirimara rheological nke ngwakọta, HPMC nwere ike ịgbatị ma ọ bụ mee ka oge nhazi oge dị ka ọ dị mkpa, na-enye mgbanwe na nhazi ihe owuwu yana hụ na arụmọrụ kachasị mma nke ihe dị n'okpuru ọnọdụ dịgasị iche iche.

Mgbochi na Efflorescence: Efflorescence, mbugharị nke nnu soluble na-aga n'elu kọmpụta ma ọ bụ masonry, nwere ike imebi ọdịdị ụlọ ma mebie ịdịte aka ha. HPMC na-enyere aka ibelata efflorescence site na ibelata permeability nke ihe owuwu yana ibelata mmegharị mmiri na nnu gbazere site na mkpụrụ. Nke a na-enyere aka ịnọgide na-adị mma nke ụlọ ahụ ma mee ka ndụ ọrụ ya dịkwuo ogologo site na igbochi ịmepụta nkwụnye ego na-adịghị mma n'elu.

HPMC na-arụ ọrụ dị iche iche na ihe owuwu ụlọ, na-enye aka na njide mmiri, ịrụ ọrụ, ịdịte aka, adhesion, mgbanwe, ịhazi oge njikwa, na iguzogide efflorescence. Ikike ya iji kwalite arụmọrụ na ogologo oge nke ihe owuwu ụlọ na-eme ka ọ bụrụ ihe mgbakwunye dị mkpa na usoro ihe owuwu nke oge a, na-eme ka owuwu nke ụlọ na-adịgide adịgide na ogologo oge.
