Ka seretse sa ho kenya mohaho le phofo ea putty, boholo ba bohloeki ba hydroxypropyl methylcellulose bo ama ka ho toba boleng ba mohaho oa boenjiniere, joale ke lintlha life tse amang bohloeki ba hydroxypropyl methylcellulose? Ho o thusa ho araba potso ena kajeno.
Ts'ebetsong ea tlhahiso ea hydroxypropyl methylcellulose, oksijene e setseng ka kettle ea karabelo e tla lebisa ho senyeha ha hydroxypropyl methylcellulose le ho fokotsa boima ba molek'hule. Leha ho le joalo, oksijene e setseng e na le moeli, kahoo ha ho thata ho kopanya limolek'hule tse robehileng hape. Sekhahla se seholo sa saturation le dikahare tsa hydroxypropyl li na le kamano e kholo, lifeme tse ling li batla ho fokotsa litšenyehelo le theko, ha li batle ho ntlafatsa litaba tsa hydroxypropyl, kahoo boleng bo ke ke ba fihla boemong ba lihlahisoa tse tšoanang tsa linaheng tse ling.
Sekhahla sa ho boloka metsi sa hydroxypropyl methylcellulose le hydroxypropyl le sona se na le kamano e ntle, 'me bakeng sa ts'ebetso eohle ea karabelo, hydroxypropyl methylcellulose e boetse e etsa qeto ea sekhahla sa ho boloka metsi sa hydroxypropyl methylcellulose. Phello ea alkalization, karo-karolelano ea chloromethane ho propylene oxide, motsoako oa alkali le karo-karolelano ea metsi ho k'hothone e hloekisitsoeng kaofela li laola ts'ebetso ea sehlahisoa.
Boleng ba lisebelisoa tse tala, phello ea alkalization, taolo ea karo-karolelano ea ts'ebetso, karo-karolelano ea solvent le phello ea neutralization, kaofela li etsa qeto ea boleng ba hydroxypropyl methyl cellulose, hydroxypropyl methyl cellulose e entsoeng ho qhibiliha ka mor'a hore lebese le koahetsoe ke maru haholo, ba bang ba tšoeu, ba bang ba mosehla, ba bang. e hlakileng le e pepeneneng. Haeba u batla ho e rarolla, fetola lintlha tse ka holimo. Ka linako tse ling asiti ea acetic e ka ama phetiso ka ho teba, asiti ea acetic e sebelisoa hantle ka mor'a ho hlapolloa, tšusumetso e kholo ka ho fetisisa kapa ts'usumetso ea karabelo e tšoana, karo-karolelano ea sistimi e tsitsitse (mongobo o mong oa lintho tse bonahalang, litaba ha lia tsitsa, joalo ka ho hlaphoheloa ha solvent), ha e le hantle, mabaka a mangata a ameha. Ka botsitso ba lisebelisoa le ts'ebetso ea basebetsi ba koetlisitsoeng, lihlahisoa tse hlahisoang li lokela ho ba tse tsitsitseng haholo. Phetisetso ha ea lokela ho feta ± 2%, 'me ho tšoana ha sehlopha se nkelang sebaka ho lokela ho laoloa hantle. Phetoho e tšoanang, phetisetso e tlameha ho ba e ntle.
Ka hona, boleng bo botle ba sehlahisoa bo khethoa ke lisebelisoa tse tala, theknoloji ea tlhahiso le lintlha tse ling. Taolo e thata feela ho tloha pheletsong e 'ngoe ho isa qetellong e ka hlahisa lihlahisoa tse nang le boleng bo tsitsitseng.
