A na-eji nrapado tile eme ihe n'ọtụtụ ebe iji tinye taịlị n'elu dị iche iche dịka mgbidi na ala. Ha dị mkpa iji hụ na njikọ siri ike n'etiti taịlị na mkpụrụ iji zere mmebi nwere ike ime, yana iji hụ na nrụnye nwere ike iguzogide nrụgide gburugburu ebe obibi dị iche iche dị ka iru mmiri, mgbanwe okpomọkụ na nhicha mgbe niile.
Otu n'ime ihe ndị a na-ejikarị na tile adhesives bụ hydroxypropylmethylcellulose (HPMC), polymer na-esite na cellulose na-enwetakarị. A maara ya maka ikike magburu onwe ya iji jide mmiri, nke na-eme ka ọ bụrụ ihe dị mma n'ime usoro nrapado tile.
Enwere ọtụtụ uru dị na iji HPMC n'ụdị nrapado tile. Ndị a gụnyere;
1. Melite ịrụ ọrụ
HPMC na-arụ ọrụ dị ka rheology modifier na cementitious formulations dị ka tile adhesives, nke pụtara na ọ nwere ike imeziwanye arụmọrụ nke tile adhesives. Ọ na-ebelata ọdịdị nke lumps na clots, nke na-eme ka nkwekọ nke ngwakọta ahụ dịkwuo mma, na-eme ka ọ dịkwuo mfe maka ndị ntinye aka na-arụ ọrụ.
2. Njide mmiri
Otu n'ime uru HPMC dị na adhesives tile bụ ikike ijide mmiri dị mma. Ọ na-ahụ na nrapado na-anọgide na-eji ya ogologo oge ma na-enyere aka ịtọ nrapado taịlị ahụ. Njirimara a na-ebelatakwa ihe ize ndụ nke mbelata mgbawa, nke a na-emekarị site na mfu mmiri n'oge nhazi.
3. Ịbawanye ike
Uru ọzọ nke iji HPMC n'ime adhesives tile bụ na ọ na-enyere aka ịbawanye ike nke ngwakọta. Mgbakwunye nke HPMC na-enyere aka mee ka ngwakọta ahụ guzosie ike, na-agbakwụnye ike na imeziwanye ogologo oge nke nrapado taịlị.
4. Chekwa oge
Adhesives tile nwere HPMC chọrọ ịgwakọta ihe nrụnye dị ntakịrị na oge ngwa n'ihi rheology emelitere. Na mgbakwunye, ogologo oge ọrụ nke HPMC na-enye pụtara na enwere ike kpuchie akụkụ buru ibu, na-ebute nrụnye tile ngwa ngwa.
5. Belata mmetụta gburugburu ebe obibi
HPMC bụ ngwaahịa sitere n'okike na nke nwere ike ịnwụ anwụ. Ya mere, iji HPMC na nrapado tile nwere ike ibelata mmetụta gburugburu ebe obibi nke nrapado ahụ wee gboo mkpa na-eto eto maka ihe eji ewu ụlọ na gburugburu ebe obibi.
Na nchịkọta, HPMC bụ ihe dị mkpa na-emepụta ihe na-emepụta akwa tile dị elu. Ikike njide mmiri ya na ndozi rheological na-enye uru gụnyere nhazi nhazi nke ọma, ike na-abawanye, mbelata mmetụta gburugburu ebe obibi na nchekwa oge. Ya mere, ụfọdụ ndị na-emepụta ihe nrapado taịlị emejuputala ojiji nke HPMC iji kwalite ike nkekọ tile na ịbawanye ogologo ike nke nrapado ha.
