N'ime ụdị ihe mgbakwunye dị iche iche eji eme ihe na-ewu mmiri, hpdropyylthylthyl na-adọrọ mmasị n'ihi ọtụtụ uru ya na ebe a na-ewu ihe na-ewu ewu. HPMC bụ usoro nke cellulose nwere akụrụngwa pụrụ iche nke nwere ike ịdị na-emetụta arụmọrụ nke adhasives ma melite ogo ọrụ nke ọrụ owuwu. Ebumnuche nke edemede a bụ inyocha ọrụ na uru nke HPMC na Tile adres na ebe a na-ewu ihe kemịkalụ, usoro nke ihe na uru ọ na-enye na ụlọ ọrụ owuwu.
1. Ngwakọta kemịkalụ na akụrụngwa nke HPMC:
Hydroxypyl Methylcelllose (HPMC) bụ polymer symetic modebere na cellose. Ọ bụ ụlọ ọrụ cellose na propylene oxide na methyl chloride, na-emepụta ogige na hydropyyl na methyl dị iche iche) jikọtara ya na ballose backbone. Odide nke nbanye (DS) nke ìgwè hydroxyl na methyl na-ekpebi ihe Njirimara nke HPMC, gụnyere viscosis, sonyere na nkwụsi ike.
HPMC nwere ezigbo mmiri soldọn ma na-etolite ụzọ na ngwọta viscus mgbe a chụsasịrị na mmiri. Agbanyeghị, akụkụ ya na-adabere na ọnọdụ okpomọkụ, na-enwe oke okpomọkụ na-amasị mgbasa. Ngwongwo a na - eme HPMC adabara maka iji ya na ụlọ akwụkwọ na - ewu ihe ebe sistemụ mmiri juru eju. Ọzọkwa, Hpmc na-enye pseudoploplastic omume na ihe ngwọta, nke pụtara na vietdị vies ya na-ebelata ngwa ngwa, si otú a na-eme ka ọ dịkwuo mfe ma na-eme ka ụzọ dị iche iche na-agbanwe agbanwe.
2. Usoro ihe omume nke seramic taramifie:
N'ụbọchị taịlị, HPMC na-arụ ọrụ dị iche iche n'ihi nhazi ihe eji eme ya na akụrụngwa ya. Otu n'ime ọrụ isi ya bụ ime ihe dị ka nke na-emegharị, melite agbanwe agbanwe na ike ọrụ nke nrapado. Site n'ịba ụba viscosity, HPMC na-enyere aka igbochi ihe mgbaze ma ọ bụ daa, na-enyere mkpuchi kwesịrị ekwesị na njikọta n'etiti taịl na mkpụrụ.
HPMC na-arụkwa ọrụ dị ka onye na-echebe mmiri, na-ahapụ nrapado iji nọgide na-enwe ezigbo mmiri n'oge usoro ọgwụgwọ. Ngwongwo a dị mkpa iji hụ na ọfụma kwesịrị ekwesị nke ihe ciment na nrapado, na-akwalite agbụ siri ike ma belata ihe ize ndụ nke cracks. Ọzọkwa, ikike na-egbochi mmiri na-eme ka oge gboo, na-ekwe ka oge zuru ezu maka idobe taịl na ndozi tupu nbata nrapado.
HPMC na-etolite ihe nkiri na-agbanwe agbanwe na-agbanwe agbanwe mgbe ị na-asa ahụ, si otú a na-eme ka ihe ndị dịnụ na-eme ka ihe dị mma. Ihe nkiri a na-eme dị ka ihe nrapado, na-akwalite njikọta n'etiti oyi akwa, taịl nile na mkpụrụ. Ọnụnọ nke HPMC na-eme ka njikọ nke njikọ dị iche iche na-eme ka ọ dịkwuo ike, na-ebelata ike ịba uru ma ọ bụ nhichapụ ka oge na-aga.
3. Mmetụta na ụlọ ọgwụ na-ewu ihe
Na mgbakwunye na tile adres, a na-ejikarị HPMC n'ọtụtụ ebe a na-ewu ewu, gụnyere ngwa agha, plasters na ndị na-arị elu. Njirimara bara ụba na-eme ka ọ bụrụ ihe dị mkpa iji mee ka arụmọrụ na ịdịgide ihe ndị a. Na ngwa agha, hpmc na-arụ ọrụ dị ka ihe omimi Rhiology, na-achịkwa omume na-asọpụta na ịdịgide nke ngwakọta ahụ. Nke a na - eme ka ngwa ngwa na ọrụ dịkwuo ike, na - eme ka ọpụpụ ma belata mkpofu ihe.
HPMC na-enyere aka melite akụrụngwa na-enweghị atụ nke ala na-eto eto ma na-asụ mkpụrụ, na-enye ohere maka ezigbo, na elu. Ike ya na-egbochi mmiri na-egbochi ngwakọta ahụ site na ihicha ihe kwesịrị ekwesị, na-akwalite ọgwụgwọ kwesịrị ekwesị ma belata ezughị oke dị ka ebe ọ bụ cracks ma ọ bụ cracks. Na mgbakwunye, HPMC na-eme ka ndọnye aka na ndọta nke plastars na ndị na-arị elu, na-ebute ike karị, ndị mara mma karị.
Ojiji nke HPMC na ụlọ ọgwụ na-ewu ihe na-etinye ihe mgbaru ọsọ na-ewu ụlọ. Site na imeziwanye usoro na mbelata ihe oriri, HPMC na-eme ka arụmọrụ arụ ọrụ na mbelata mkpofu. Ọzọkwa, ọrụ ya na ịkwalite ihe owuwu ụlọ na-enyere aka ịgbatị ndụ ụlọ, si otú a belata mmezi ma ọ bụ dochie anya.
Hydroxypyl Methylcelllose (HPMC) na-arụ ọrụ dị mkpa na adle tile nke ọgbara ọhụrụ na ụlọ ọrụ na-enye aka melite arụmọrụ, na-enye ohere na ịdị ogologo. Ihe mejupụtara kemịkal ya pụrụ iche na akụrụngwa ya na-eme ka ọ bụrụ ihe dị ka nke na-eche nche, mmiri na-ejigide onye na-echekwa na nkwalite adhesion. Na mgbakwunye, HPMC na-eme ka ihe ndị na-ewu ihe na-ewu ihe na-ewu ihe na-ewu ihe na-ewu ewu iji kwado ma hụ na ịdị n'otu nke ngwaahịa a rụchara.
Ojiji nke HPMC na ụlọ ọrụ na-ewu ihe na-egosi mkpa ọ dị anya dị ka ihe mgbakwunye na-eme ka mma na nkwado nke ụlọ. Dị ka omume iwu na-aga n'ihu na-aga n'ihu, mkpa maka azịza ọhụụ iji meziwanye arụmọrụ na ịdị ogologo ga-ebugharị nyocha na mmepe nke usoro HPMC. Site n'ikike ikike HPMC, ụlọ ọrụ na-ewu ụlọ nwere ike ịchọpụta ọganihu arụmọrụ ma na-atụnye ụtụ maka mmepe nke ebe obibi na ebe obibi.
