umbuzo :
UPutty uziva enzima
Ngethuba lokwakhiwa kwe-putty, abanye abantu baya kuhlangabezana nemeko yokuba isandla siziva sinzima.Siyintoni isizathu esingqalileyo?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
Ubuncinci 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!
