Umgubo we-putty powder udla ngokubhekisa kwinto yokuba umphezulu we-putty coating uba yi-powder uze uwe emva kokwakhiwa, nto leyo eya kuchaphazela amandla okubopha kwe-putty kunye nokuqina kwe-coating. Le nto ye-powdering inxulumene nezinto ezininzi, enye yazo kukusetyenziswa kunye nomgangatho we-hydroxypropyl methylcellulose (HPMC) kwi-putty powder.
1. Indima ye-HPMC kumgubo we-putty
I-HPMC, njengesongezelelo esisetyenziswa kakhulu, isetyenziswa kakhulu kwizixhobo zokwakha, kuquka umgubo we-putty, i-mortar, i-glue, njl. Imisebenzi yayo ephambili ibandakanya:
Isiphumo sokutyeba: I-HPMC inokunyusa ukuhambelana komgubo we-putty, yenze ulwakhiwo lube lula kwaye iphephe ukutyibilika okanye ukuhamba komgubo we-putty ngexesha lokwakha.
Ukugcinwa kwamanzi: I-HPMC inokugcinwa kakuhle kwamanzi, nto leyo enokwandisa ukusebenza kwe-putty powder kwaye ithintele i-putty ekulahlekelweni ngamanzi ngokukhawuleza ngexesha lenkqubo yokomisa, nto leyo ekhokelela ekuqhekekeni okanye ekuncipheni.
Ukunamathela okuphuculweyo: I-HPMC inokunyusa ukunamathela komgubo we-putty, ukuze ikwazi ukunamathela eludongeni okanye komnye umphezulu we-substrate, inciphise ukwenzeka kweengxaki ezinje ngokugqobhoza nokuwa.
Ukuphucula ukusebenza kolwakhiwo: Ukongeza i-HPMC kumgubo we-putty kunokuphucula ukutyibilika kunye nokuqina kolwakhiwo, kwenze imisebenzi yokwakha ibe lula, kwaye kunciphise inkunkuma.
2. Izizathu zokucolwa komgubo we-putty
Ukucolwa kwe-putty powder yingxaki eqhelekileyo enezizathu ezinzima, ezinokunxulunyaniswa nezi zinto zilandelayo:
Ingxaki ye-substrate: Ukufunxwa kwamanzi kwe-substrate kunamandla kakhulu, nto leyo ebangela ukuba i-putty ilahlekelwe ngumswakama ngokukhawuleza kwaye iqine ngokupheleleyo, nto leyo ebangela ukuba i-pulverization ingasebenzi.
Ingxaki yefomula yePutty: Ifomula engalunganga yePutty powder, efana nomlinganiselo ongafanelekanga wezinto ezisebenzisa isamente (ezifana nesamente, igypsum, njl.njl.), iya kuchaphazela amandla kunye nokuqina kwePutty.
Ingxaki yenkqubo yokwakha: Ukwakhiwa okungacwangciswanga, ubushushu obuphezulu okanye ukufuma okuphantsi kunokubangela ukuba umgubo we-putty ucolwe ngexesha lenkqubo yokomisa.
Ukugcinwa okungafanelekanga: Ukungaphumeleli ukugcina i-putty ngexesha emva kokwakhiwa okanye ukuqhubeka ngaphambi kwexesha kwinkqubo elandelayo kunokubangela ukuba umgubo we-putty ucolwe ngaphandle kokuba womiswe ngokupheleleyo.
3. Ubudlelwane phakathi kwe-HPMC kunye nokucolwa kwe-pulverization
Njengesixhobo sokutyebisa kunye nesokugcina amanzi, ukusebenza kwe-HPMC kwi-putty powder kunempembelelo ngqo kumgangatho we-putty. Impembelelo ye-HPMC kwi-powdering ibonakala kakhulu kwezi zinto zilandelayo:
(1) Impembelelo yokugcinwa kwamanzi
Ukufuthwa komgubo we-putty kudla ngokunxulunyaniswa nokuphuma kwamanzi ngokukhawuleza kwi-putty. Ukuba ubungakanani be-HPMC eyongeziweyo alwanele, umgubo we-putty ulahlekelwa ngamanzi ngokukhawuleza ngexesha lenkqubo yokomisa kwaye awuzange uqine ngokupheleleyo, nto leyo ebangela ukuba umphezulu ube yi-powder. Ipropati yokugcina amanzi ye-HPMC inceda i-putty igcine umswakama ofanelekileyo ngexesha lenkqubo yokomisa, ivumela i-putty ukuba iqine kancinci kwaye ithintele umgubo obangelwa kukulahleka kwamanzi ngokukhawuleza. Ke ngoko, ukugcinwa kwamanzi kwe-HPMC kubalulekile ekunciphiseni umgubo.
(2) Impembelelo yesiphumo sokutyeba
I-HPMC inokunyusa ukuhambelana kwe-putty powder, ukuze i-putty inamathele ngokulinganayo kwi-substrate. Ukuba umgangatho we-HPMC awulunganga okanye ayisetyenziswanga kakuhle, iya kuchaphazela ukuhambelana kwe-putty powder, yenze ukuba ukunyibilika kwayo kube kubi, nto leyo ebangela ukungalingani kunye nobukhulu obungalinganiyo ngexesha lokwakhiwa, nto leyo enokubangela ukuba i-putty powder yome ngokukhawuleza kwindawo ethile, nto leyo ebangela ukuba i-powder ibe yi-powder. Ukongeza, ukusetyenziswa kakhulu kwe-HPMC kuya kubangela ukuba umphezulu we-putty powder ube bushelelezi kakhulu emva kokwakhiwa, nto leyo echaphazela ukunamathela kwi-coating kwaye ibangele i-powder yomphezulu.
(3) Ukusebenzisana nezinye izinto
Kwi-putty powder, i-HPMC idla ngokusetyenziswa kunye nezinye izinto ezisebenzisa isamente (ezifana nesamente, i-gypsum) kunye nezizalisi (ezifana ne-calcium powder enzima, i-talcum powder). Ubungakanani be-HPMC esetyenzisiweyo kunye nokusebenzisana kwayo nezinye izinto kunempembelelo enkulu ekusebenzeni kwe-putty iyonke. Ifomula engafanelekanga inokukhokelela ekubeni i-putty powder ingabi namandla aneleyo kwaye ekugqibeleni ikhokelele ekufakweni kwe-powder. Ukusetyenziswa kwe-HPMC ngokufanelekileyo kunokunceda ukuphucula ukusebenza kwe-bonding kunye namandla e-putty kwaye kunciphise ingxaki ye-powder ebangelwa zizinto ezinganeleyo okanye ezingalinganiyo zesamente.
4. Iingxaki zomgangatho we-HPMC zikhokelela ekugayweni komgubo
Ukongeza kubungakanani be-HPMC esetyenzisiweyo, umgangatho we-HPMC ngokwawo unokuchaphazela ukusebenza kwe-putty powder. Ukuba umgangatho we-HPMC awufikeleli kwinqanaba eliqhelekileyo, njengokucoceka okuphantsi kwe-cellulose kunye nokusebenza kakubi kokugcinwa kwamanzi, kuya kuchaphazela ngqo ukugcinwa kwamanzi, ukusebenza kolwakhiwo kunye namandla e-putty powder, kwaye kwandise umngcipheko wokufuthwa nge-powder. I-HPMC engaphantsi ayinzima nje kuphela ukubonelela ngeziphumo zokugcina amanzi ezizinzileyo kunye nokuqina, kodwa inokubangela ukuqhekeka komphezulu, ukufuthwa nge-powder kunye nezinye iingxaki ngexesha lenkqubo yokomisa i-putty. Ke ngoko, ukukhetha i-HPMC esemgangathweni ophezulu kubalulekile ukuze kuthintelwe iingxaki zokufuthwa nge-powder.
5. Impembelelo yezinye izinto ekugayeni umgubo
Nangona i-HPMC idlala indima ebalulekileyo kwi-putty powder, i-powdering idla ngokuba yimiphumo edibeneyo yezinto ezininzi. Ezi zinto zilandelayo zinokubangela i-powdering:
Iimeko zendalo: Ukuba ubushushu kunye nokufuma kwendawo yokwakha kuphezulu kakhulu okanye kuphantsi kakhulu, kuya kuchaphazela isantya sokomisa kunye nesiphumo sokugqibela sokuphiliswa komgubo we-putty.
Unyango olungafanelekanga lwe-substrate: Ukuba i-substrate ayicocekanga okanye umphezulu we-substrate ufunxa amanzi amaninzi, oku kuya kuchaphazela ukunamathela komgubo we-putty kwaye kubangele umgubo.
Ifomula yepowder ye-putty engaqikelelweyo: Kusetyenziswa i-HPMC eninzi kakhulu okanye encinci kakhulu, kwaye umlinganiselo wezinto ezisebenzisa isamente awufanelekanga, nto leyo eya kukhokelela ekubeni i-putty powder inganamatheli ngokwaneleyo kwaye ingaqini, nto leyo ebangela ukuba i-putty powder ibe yipowder.
Ingxaki yokufutha i-putty powder inxulumene kakhulu nokusetyenziswa kwe-HPMC. Umsebenzi ophambili we-HPMC kwi-putty powder kukugcina amanzi kunye nokuqina. Ukusetyenziswa ngokufanelekileyo kunokuthintela ngempumelelo ukwenzeka kwe-powder. Nangona kunjalo, ukwenzeka kwe-powder akuxhomekanga kwi-HPMC kuphela, kodwa nakwizinto ezifana nefomyula ye-putty powder, unyango lwe-substrate, kunye nendawo yokwakha. Ukuze kuthintelwe ingxaki ye-powder, kubalulekile nokukhetha i-HPMC esemgangathweni ophezulu, uyilo lwefomyula olufanelekileyo, iteknoloji yokwakha yesayensi kunye nendawo yokwakha elungileyo.
