Amfani da HPMC a cikin foda na putty

1. Menene dacewar danko na HPMC?

——Amsa: Gabaɗaya, yuan 100,000 ya isa ga foda na putty. Bukatun turmi sun fi yawa, kuma ana buƙatar yuan 150,000 don sauƙin amfani. Bugu da ƙari, mafi mahimmancin aikin HPMC shine riƙe ruwa, sannan kauri. A cikin foda na putty, matuƙar riƙe ruwa yana da kyau kuma ɗanɗanon ya yi ƙasa (70,000-80,000), haka nan yana yiwuwa. Tabbas, mafi girman ɗanɗanon, mafi kyawun riƙe ruwa. Lokacin da ɗanɗanon ya wuce 100,000, ɗanɗanon zai shafi riƙe ruwa. Ba da yawa ba.

2. Menene manyan alamun fasaha naHPMC?

——Amsa: Yawan sinadarin Hydroxypropyl da kuma yawan sinadarin da ke cikinsa, yawancin masu amfani da shi suna damuwa da waɗannan alamomi guda biyu. Waɗanda ke da yawan sinadarin hydroxypropyl gabaɗaya suna da ingantaccen riƙe ruwa. Wanda ke da yawan sinadarin da ke cikinsa yana da ingantaccen riƙe ruwa, idan aka kwatanta da (ba gaba ɗaya ba), kuma wanda ke da yawan sinadarin da ke cikinsa ya fi kyau a yi amfani da shi a turmi na siminti.

3. Menene babban aikin amfani da HPMC a cikin foda na putty, kuma shin hakan yana faruwa ne ta hanyar sinadarai?

——Amsa: A cikin foda na putty, HPMC tana taka rawa uku na kauri, riƙe ruwa da ginawa. Kauri: Ana iya ƙara cellulose don dakatarwa da kuma kiyaye maganin iri ɗaya sama da ƙasa, da kuma tsayayya da yin kasa. Rike ruwa: sa foda na putty ya bushe a hankali, kuma yana taimaka wa tokar calcium ta amsa a ƙarƙashin aikin ruwa. Ginawa: Cellulose yana da tasirin shafawa, wanda zai iya sa foda na putty ya sami kyakkyawan tsari. HPMC ba ya shiga cikin duk wani halayen sinadarai, amma yana taka rawa kawai. Ƙara ruwa a cikin foda na putty da sanya shi a bango martanin sinadarai ne, saboda ana samar da sabbin abubuwa. Idan ka cire foda na putty a bango daga bango, ka niƙa shi zuwa foda, ka sake amfani da shi, ba zai yi aiki ba saboda an samar da sabbin abubuwa (calcium carbonate). Babban abubuwan da ke cikin foda na ash calcium sune: cakuda Ca(OH)2, CaO2 da ƙaramin adadin CaCO3, CaO+H2O=Ca(OH)2 —Ca(OH)2+CO2=CaCO3↓+H2O Calcium na ash yana cikin ruwa da iska A ƙarƙashin aikin CO2, ana samar da calcium carbonate, yayin da HPMC ke riƙe ruwa kawai, yana taimakawa wajen inganta amsawar ash calcium, kuma baya shiga cikin kowane martani da kansa.

4. HPMC wani sinadari ne na cellulose wanda ba ionic ba, to menene ba ionic ba?

——Amsa: A taƙaice, abubuwan da ba ion ba ne, abubuwa ne da ba za su yi ion a cikin ruwa ba. Ionization yana nufin tsarin da ake raba electrolyte zuwa ions masu caji waɗanda za su iya motsawa cikin 'yanci a cikin wani takamaiman sinadarin sinadarai (kamar ruwa, barasa). Misali, sodium chloride (NaCl), gishirin da muke ci kowace rana, yana narkewa a cikin ruwa kuma yana yin ionize don samar da ions masu motsi kyauta (Na+) waɗanda ke da caji mai kyau da ions masu chloride (Cl) waɗanda ke da caji mara kyau. Wato, lokacin da aka sanya HPMC a cikin ruwa, ba zai rabu zuwa ions masu caji ba, amma yana wanzuwa a cikin nau'in ƙwayoyin halitta.

5. Akwai wata alaƙa tsakanin digon foda na putty da HPMC?

——Amsa: Asarar foda na foda yana da alaƙa da ingancin sinadarin ash, kuma ba shi da alaƙa da HPMC. Ƙarancin sinadarin calcium na sinadarin toka da kuma rashin daidaiton rabon CaO da Ca(OH)2 a cikin sinadarin toka zai haifar da asarar foda. Idan yana da alaƙa da HPMC, to idan riƙe ruwa na HPMC bai yi kyau ba, zai kuma haifar da asarar foda.

6. Yadda ake zaɓar wanda ya daceHPMCdon dalilai daban-daban?

——Amsa: Aiwatar da foda na putty: buƙatun sun yi ƙasa kaɗan, kuma ɗanɗanon ya isa 100,000, wanda hakan ya isa. Abu mafi mahimmanci shine a kiyaye ruwa da kyau. Aiwatar da turmi: buƙatun da suka fi girma, ɗanɗanon da ya fi girma, 150,000 ya fi kyau. Aiwatar da manne: ana buƙatar samfuran nan take masu ɗanɗanon da ya fi girma.
