Focus on Cellulose ethers

Indlela yokuphucula imvakalelo enzima yesandla sokukrala kweputty

umbuzo :

UPutty uziva enzima

Ngethuba lokwakhiwa kwe-putty, abanye abantu baya kuhlangabezana nemeko yokuba isandla siziva sinzima. Siyintoni isizathu esikhethekileyo? Inokuphuculwa njani?

Izizathu eziqhelekileyo zokuba kutheni i-putty ivakalelwa kukuba:

1. Ukusetyenziswa okungafanelekanga kwemodeli ye-viscosity ye-cellulose ether:

Kule meko, i-viscosity ye-cellulose ether iphezulu kakhulu, kwaye i-putty eyenziwe iya kuziva inzima ngexesha lenkqubo yokukrazula;

Esinye isizathu kukuba ngexesha lokwakhiwa kwehlobo, ukusetyenziswa kwe-hydroxypropyl methylcellulose ether kunye nokumelana nokushisa okuphezulu kunokubangela ukuba i-putty ilahlekelwe yi-viscosity, eya kuchaphazela ukuvakalelwa kokwakhiwa.

2. Umlinganiselo ongalunganga okanye ukucolwa komgubo:

Ngokuqhelekileyo, kukho izinto ezininzi ze-inorganic gelling, okanye ubuhle bomhluzi okhethiweyo bulungile kakhulu, obulungele ukunamathela kwimela;

Kwakhona kunokwenzeka ukuba ukuze kuncitshiswe iindleko, akukho okanye ngaphantsi kwezongezo zokuphucula ukuvakalelwa kwesandla zongezwa, ezifana ne-starch ethers kunye ne-thixotropic lubricants.

Iindlela zokuphucula 1

Umlinganiselo ofanelekileyo wezinto ezikrwada kunye nokukhetha okuhle

Ubuhle bezinto eziluhlaza ziyakwazi ukulawulwa kwi-150-200 mesh, kwaye ukucocwa kwe-filler ingaba yi-325 mesh, kungekhona kakhulu;

Ubungakanani bepolyvinyl yotywala obuyimpuphu ayiyi kudlula i-6%;

Kukwayimfuneko ukufunda ukunciphisa ubungakanani bezinto zesamente ezingaphiliyo. Ngokuqhelekileyo, kwanele ukulawula i-samente kwi-28% -32%, kwaye usebenzise izongezo zokuphuhlisa ngokupheleleyo ukusebenza kwayo.

Indlela yokuphucula 2

Khetha i-ether cellulose efanelekileyo

Ngokuqhelekileyo, sincoma i-hydroxyethyl methyl cellulose ether kunye nokusebenza okungcono, enokumelana nokushisa okuphezulu kwaye inokulungelelaniswa kakuhle nokwakhiwa kwehlobo kunye nokunciphisa iindleko zokutshintshiselwa kwebusika kunye nehlobo;

Into ephambili kukuba ukhethe i-ether ye-cellulose ene-viscosity efanelekileyo. Ngokuqhelekileyo, i-ether ye-cellulose ene-viscosity ye-80,000 ukuya kwi-100,000 yanele kwi-putty powder, kodwa isixa se-cellulose ether esongeziweyo kufuneka sigqitywe ngokusebenzisa iimvavanyo ezifanelekileyo zokwakha!

Iindlela zokuphucula 3

Yongeza izongezo ukuphucula ukuva kwesandla

Ekugqibeleni, sinokuqwalasela ukongeza isitashi ether okanye i-thixotropic lubricant (bentonite) ukuphucula ukuvakalelwa kodaka;

Khumbula: indibaniselwano yefomula yenzululwazi sisitshixo sokusombulula ingxaki!
