Ngaba i-methylcellulose i-antifoaming agent?

I-Methylcellulose yinto eqhelekileyo evela kwi-cellulose esetyenziswa ngokubanzi kumayeza, ukutya kunye neshishini. I-polymer e-soluble yamanzi yenziwe ngokukodwa kwi-cellulose yezityalo zendalo ngokuguqulwa kweekhemikhali, kwaye inezinto ezininzi ezikhethekileyo, ezifana nokuqina, i-gelling, ukumiswa, ukwenza ifilimu kunye nokugcinwa kwamanzi.

Iimpawu kunye nokusetyenziswa kwe-methylcellulose

I-Thickener kunye ne-gelling agent: Kwishishini lokutya, i-methylcellulose idla ngokusetyenziswa njenge-thickener kunye ne-gelling agent ukunceda ukuphucula ukuthungwa kunye nokunambitha kwemveliso. Ngokomzekelo, kwiimveliso ezifana ne-ayisikrimu, i-jam kunye nokugqoka isaladi, i-methylcellulose inokubonelela nge-viscosity enhle kunye nokuphucula ukuzinza kwemveliso.

Abathwali beziyobisi kunye nabancedisi: Kwishishini lamachiza, i-methylcellulose isoloko isetyenziswa njenge-excipient yeziyobisi, njenge-binder kunye ne-filler yeepilisi. Isenokusetyenziswa njenge-arhente eqhubekayo yokukhululwa kwechiza ukulawula izinga lokukhululwa kweyeza kunye nokuqinisekisa ukuzinza kunye nokuqina kwesiphumo sechiza.

Ukusetyenziswa kwizinto zokwakha: Kwintsimi yezinto zokwakha, i-methylcellulose isetyenziswe njenge-thickener kunye ne-agent egcina amanzi kwi-samente, i-gypsum kunye neengubo zokugcoba ukuphucula ukusebenza kokwakhiwa kunye nokuqina kwezinto.

Umahluko phakathi kwe-methylcellulose kunye ne-antifoaming agents

Ii-Antifoaming agents ziyiklasi yeekhemikhali ezisetyenziselwa ukucinezela okanye ukuphelisa amaqamza kulwelo, kwaye zixhaphake ngokufumaneka ekusetyenzweni kokutya, kumayeza, kwizinto zokuthambisa, ukwenza amaphepha, iikhemikhali, kunye nokunyangwa kwamanzi. I-Antifoaming agents ngokuqhelekileyo isebenza ngokunciphisa ukunyanzeliswa komphezulu we-liquid ukukhusela ukubunjwa kwe-foam, okanye ngokukhuthaza ukuwa ngokukhawuleza kwe-foam eyenziwe. Ii-antifoaming agents eziqhelekileyo ziquka ioli ye-silicone, i-polyethers, i-fatty acid esters, kunye neengqungquthela ezithile eziqinileyo, ezifana ne-silicon dioxide.

Nangona kunjalo, i-methylcellulose ayisiyonto ye-antifoaming kwindalo. Nangona i-methylcellulose inokwenza isisombululo se-viscous xa inyibilika emanzini, kwaye i-viscosity yesi sisombululo inokuchaphazela ukubunjwa kwe-foam kwezinye iimeko, ayinayo indawo esebenzayo ye-antifoaming agents. Ngamanye amazwi, umsebenzi oyintloko we-methylcellulose kukuba usebenza njenge-thickener, i-gelling agent, i-agent yokumisa, njl., Kunokuba isetyenziswe ngokuthe ngqo ukucinezela okanye ukuphelisa i-foam.

Ukudideka okunokwenzeka kunye namatyala akhethekileyo

Nangona i-methylcellulose ingeyiyo i-antifoaming agent, kwezinye iifomyula ezithile okanye iimveliso, inokuchaphazela ngokungathanga ngqo ukuziphatha kwe-foam ngenxa yesiphumo sayo sokuqina kunye neempawu zesisombululo. Ngokomzekelo, kwezinye ukutya okanye ukuxutywa kweziyobisi, i-viscosity ephezulu ye-methylcellulose inokunciphisa ukubunjwa kweebhubhu okanye ibangele ukuba iibhubhu eziye zenziwe ukuba zichithe ngokukhawuleza. Nangona kunjalo, le mpembelelo ayikuvumeli ukuba ihlelwe njenge-agent ye-antifoaming ngenxa yokuba indlela yayo ephambili yokusebenza ihluke kakhulu kwindalo yeekhemikhali kunye nendlela yokusebenza ye-antifoaming agents.

I-Methylcellulose isetyenziswa ngokubanzi kwi-cellulose derivative enemisebenzi emininzi, kodwa ayithathwa njenge-antifoaming agent. Nangona inokuba nefuthe kwindlela yokuziphatha egwebu amagwebu kwiimeko ezithile ezithile, oku akubhekiseli ekusetyenzisweni kwayo okungundoqo okanye indlela yokwenza. I-Antifoaming agents ngokubanzi zinomsebenzi othile ongaphezulu kunye nobuchule bokulawula i-foam, ngelixa i-methylcellulose isetyenziselwa ukuqina, i-gelling, ukumiswa kunye nokugcinwa kwamanzi. Ngoko ke, xa usebenzisa i-methylcellulose, ukuba isiphumo esicacileyo se-antifoaming siyadingeka, i-agent ekhethekileyo ye-antifoaming kufuneka ikhethwe ukuba isetyenziswe ngokudibeneyo.
