HPMC ikoreshwa mu gusuka ipamba ku rukuta

1. Ni ibihe bimenyetso by'ingenzi bya tekiniki bya hydroxypropyl methyl cellulose (HPMC)?

HPMC Hydroxypropyl ifite ubunini n'ubunini, abakoresha benshi bahangayikishijwe n'ibi bimenyetso bibiri. Ubusanzwe amazi agumana ni meza ku bafite ubunini bwa hydroxypropyl. Ubunini butuma amazi agumana, ubunini butuma agumana, (aho kuba bunini) ni bwiza, kandi ubunini butuma agumana, ni byiza gukoresha mu gusya sima.

2. Ni iyihe nshingano nyamukuru yo gukoresha HPMC muri puti yo ku rukuta?

Muri puti yo ku rukuta, HPMC ifite imirimo itatu: gukurura, kubika amazi no kubaka.

Ububyimbirwe: Selilulose ishobora gukongerwa kugira ngo ikomeze guhagarara neza, kandi irinde kugwa. Amazi agumana: ituma putty yo ku rukuta yumuka buhoro buhoro, kandi igafasha kalisiyumu y'umukara gukora iyo amazi arimo gukora. Imiterere: Selilulose ifite ubushobozi bwo gusiga amavuta, bigatuma putty yo ku rukuta ikora neza.

3. Ese igitonyanga cya putty yo ku rukuta gifitanye isano na HPMC?

Igabanuka rya putty yo ku rukuta ahanini rifitanye isano n'ubwiza bwa kalisiyumu y'ivu, ariko ntabwo rifitanye isano na HPMC. Niba calcium iri mu ivu rya kalisiyumu n'ikigereranyo cya CaO na Ca(OH)2 muri kalisiyumu y'ivu bidakwiye, bizatera ifu itakaye. Niba bifitanye isano na HPMC, amazi make ya HPMC na yo azatuma ifu igabanuka.

4. Hydroxypropyl methyl cellulose (HPMC) ingana iki muri putty yo ku rukuta?

Ingano ya HPMC ikoreshwa mu bikorwa nyabyo iratandukanye bitewe n'ikirere, ubushyuhe, ubwiza bwa kalisiyumu y'ivu ryo mu gace runaka, formula ya putty yo ku rukuta, n' "ubwiza busabwa n'abakiriya". Muri rusange, hagati ya kg 4 na kg 5. Urugero: putty yo ku rukuta ya Beijing ipima ibiro 5; Guizhou ipima ibiro 5 mu mpeshyi na kg 4.5 mu gihe cy'itumba; Yunnan ni nto, ubusanzwe ipima ibiro 3 kugeza kuri kg 4 n'ibindi.

5. Ni ubuhe buryo bukwiye bwo gupima hydroxypropyl methyl cellulose (HPMC)?

Ubusanzwe, icyuma gifunga inkuta kiba gifite agaciro ka 100.000, ariko sima irasaba imbaraga nyinshi, kandi ifata 150.000 kugira ngo ikore. Byongeye kandi, uruhare runini rwa HPMC ni ukubungabunga amazi, hagakurikiraho gukuba. Muri icyuma gifunga inkuta, igihe cyose amazi abungabunga neza, ubukana buba buri hasi (70-80.000), birashoboka kandi, birumvikana ko ubukana buba buri hejuru, kandi ubukana bw'amazi buba bwiza kurushaho. Iyo ubukana burenze 100.000, ubukana ntacyo bugira ku bukana bw'amazi.

6. Ni gute wahitamo hydroxypropyl methylcellulose (HPMC) ikwiye mu bikorwa bitandukanye?

Gukoresha puti yo ku rukuta: ibisabwa ni bike, ubushyuhe ni 100.000, birahagije, icy'ingenzi ni ugukomeza amazi neza. Gukoresha sima: ibisabwa byinshi, ubushyuhe bwinshi, biruta 150.000, gukoresha kole: ibintu bishonga vuba, ubushyuhe bwinshi.

7. Gukoresha HPMC muri puti yo ku rukuta, ni iki gituma puti yo ku rukuta ikora uduheri?

HPMC igira uruhare rutatu mu gupfunyika kw'inkuta: gukomera, kubika amazi no kubaka. Ntukifatanye mu gikorwa icyo ari cyo cyose. Impamvu zitera uduheri:

(1) Amazi menshi cyane ashyirwamo.

(2) Igice cyo hasi nticyumye, kandi hari ikindi gice cyacyo cyakwaruweho, nacyo cyoroshye gufuro.
