I-powdering ye-putty powder ngokuqhelekileyo ibhekisela kwinto yokuba umphezulu wengubo ye-putty uba ngumgubo kwaye iwele emva kokwakhiwa, okuya kuchaphazela amandla okubambisana kwe-putty kunye nokuqina kwengubo. Le nto ye-powdering ihambelana nezinto ezininzi, enye yazo kukusetyenziswa kunye nomgangatho we-hydroxypropyl methylcellulose (HPMC) kwi-putty powder.
1. Indima ye-HPMC kwi-putty powder
I-HPMC, njengesongezo esisetyenziswa ngokuqhelekileyo, sisetyenziswa ngokubanzi kwizinto zokwakha, kuquka umgubo we-putty, udaka, iglue, njl. Imisebenzi yayo ephambili ibandakanya:
Isiphumo sokuqina: I-HPMC inokunyusa ukuhambelana kwe-putty powder, ukwenza ulwakhiwo lube lula kwaye lugweme ukutyibilika okanye ukuhamba kwe-putty powder ngexesha lokwakha.
Ukugcinwa kwamanzi: I-HPMC inokugcinwa kwamanzi okulungileyo, okunokwandisa ukusebenza kwe-putty powder kunye nokuthintela i-putty ekulahlekelweni kwamanzi ngokukhawuleza ngexesha lokumisa, okubangelwa ukuqhekeka okanye ukucutheka.
Ukubambelela okuphuculweyo: I-HPMC inokunyusa ukudibanisa kwe-putty powder, ukwenzela ukuba ikwazi ukunamathela kakuhle eludongeni okanye kwenye indawo ye-substrate, ukunciphisa ukuvela kweengxaki ezifana nokugoba kunye nokuwa.
Ukuphucula ukusebenza kolwakhiwo: Ukongeza i-HPMC kwi-putty powder kunokuphucula ubumanzi kunye neplastiki yokwakha, ukwenza imisebenzi yokwakha ibe lula, kunye nokunciphisa inkunkuma.
2. Izizathu ze-putty powder pulverization
I-Putty powder pulverization yingxaki eqhelekileyo enezizathu ezinzima, ezinokunxulumana nezi zinto zilandelayo:
Ingxaki ye-Substrate: Ukufunxwa kwamanzi kwi-substrate kunamandla kakhulu, kubangela ukuba i-putty ilahlekelwe ngumswakama ngokukhawuleza kwaye iqiniswe ngokungaphelelanga, okukhokelela ekuhlambulukeni.
Ingxaki yefomula ye-Putty: Ifomula engafanelekanga ye-putty powder, njengenxalenye engafanelekanga yezinto ze-cementitious (ezifana ne-samente, i-gypsum, njl.), iya kuchaphazela amandla kunye nokuqina kwe-putty.
Ingxaki yenkqubo yokwakha: Ukwakhiwa ngokungaqhelekanga, ubushushu obuphezulu be-ambient okanye ukufuma okuphantsi kunokubangela ukuba i-putty powder ibhule ngexesha lenkqubo yokomisa.
Ukugcinwa okungafanelekanga: Ukungaphumeleli ukugcina i-putty ngexesha emva kokwakhiwa okanye ukuqhubela phambili kwinkqubo elandelayo kunokubangela ukuba i-putty powder ibhule ngaphandle kokuba yomiswe ngokupheleleyo.
3. Ubudlelwane phakathi kwe-HPMC kunye ne-pulverization
Njenge-ejenti ye-thickener kunye nokugcina amanzi, ukusebenza kwe-HPMC kwi-putty powder kunempembelelo ngqo kumgangatho we-putty. Impembelelo ye-HPMC kumgubo ibonakaliswa ikakhulu kule miba ilandelayo:
(1) Impembelelo yokugcinwa kwamanzi
I-powdering ye-putty powder idla ngokuhambelana nokunyuka ngokukhawuleza kwamanzi kwi-putty. Ukuba isixa se-HPMC esongeziweyo asanelanga, i-putty powder ilahlekelwa ngamanzi ngokukhawuleza ngexesha lokumisa kwaye ihluleka ukuqinisa ngokupheleleyo, okubangelwa umgubo womphezulu. Ipropathi yokugcinwa kwamanzi ye-HPMC inceda i-putty igcine ukufuma okufanelekileyo ngexesha lenkqubo yokomisa, ivumela i-putty ukuba ibe lukhuni ngokuthe ngcembe kwaye ithintele umgubo obangelwa ukulahleka kwamanzi ngokukhawuleza. Ke ngoko, ukugcinwa kwamanzi kwe-HPMC kubalulekile ekunciphiseni umgubo.
(2) Impembelelo yesiphumo sokuqina
I-HPMC inokunyusa ukuhambelana kwe-putty powder, ukwenzela ukuba i-putty ifakwe ngokulinganayo kwi-substrate. Ukuba umgangatho we-HPMC uhlwempuzekile okanye usetyenziswe ngokungafanelekanga, uya kuchaphazela ukuhambelana kwe-putty powder, okwenza umbane wayo ube mandundu, okubangela ukungalingani kunye nobukhulu obungalinganiyo ngexesha lokwakha, oku kunokubangela ukuba i-putty powder yome ngokukhawuleza kwindawo, ngaloo ndlela. ukwenza umgubo. Ukongeza, ukusetyenziswa ngokugqithiseleyo kwe-HPMC kuya kubangela ukuba umphezulu we-putty powder ube mpuluswa kakhulu emva kokwakhiwa, okuchaphazela ukunamathela kunye ne-coating kunye ne-powdering surface.
(3) Intsebenziswano nezinye izinto
Kwi-putty powder, i-HPMC idla ngokusetyenziswa ngokudibeneyo kunye nezinye izinto ze-cementitious (ezifana ne-samente, i-gypsum) kunye nezigcwalisi (ezifana ne-calcium powder enzima, i-talcum powder). Isixa se-HPMC esisetyenzisiweyo kunye ne-synergy kunye nezinye izinto zinempembelelo enkulu ekusebenzeni ngokubanzi kwe-putty. Ifomula engafanelekanga inokukhokelela kumandla anganeleyo e-putty powder kwaye ekugqibeleni iholele ekubeni ngumgubo. Ukusetyenziswa kwe-HPMC okunengqiqo kunokunceda ukuphucula ukusebenza kwe-bonding kunye namandla e-putty kunye nokunciphisa ingxaki yomgubo obangelwa zizinto ezingonelanga okanye ezingalinganiyo zesamente.
4. Iingxaki zomgangatho we-HPMC zikhokelela ekubeni ngumgubo
Ukongeza kwixabiso le-HPMC elisetyenzisiweyo, umgangatho we-HPMC ngokwawo unokuchaphazela nokusebenza kwe-putty powder. Ukuba umgangatho we-HPMC awukho kumgangatho, njengokucoceka kwe-cellulose ephantsi kunye nokusebenza kakubi kokugcinwa kwamanzi, kuya kuchaphazela ngokuthe ngqo ukugcinwa kwamanzi, ukusebenza kokwakhiwa kunye namandla e-putty powder, kunye nokwandisa umngcipheko wokuba ngumgubo. I-HPMC ephantsi ayinzima nje kuphela ukubonelela ukugcinwa kwamanzi okuzinzileyo kunye nemiphumo yokuqina, kodwa inokubangela ukuqhekeka kwendawo, umgubo kunye nezinye iingxaki ngexesha lokumisa i-putty. Ke ngoko, ukukhetha umgangatho ophezulu we-HPMC kubalulekile ukunqanda iingxaki zomgubo.
5. Impembelelo yezinye izinto kumgubo
Nangona i-HPMC idlala indima ebalulekileyo kwi-putty powder, i-powdering idla ngokuba ngumphumo odibeneyo wezinto ezininzi. Ezi zinto zilandelayo zinokubangela umgubo:
Iimeko zokusingqongileyo: Ukuba ubushushu kunye nokufuma kwendawo yokwakha kuphezulu kakhulu okanye kuphantsi kakhulu, kuya kuchaphazela isantya sokumisa kunye nesiphumo sokugqibela sokunyanga seputty powder.
Ukunyangwa kwe-substrate engafanelekanga: Ukuba i-substrate ayihlambulukanga okanye indawo ye-substrate ithatha amanzi amaninzi, iya kuchaphazela ukunamathela kwe-putty powder kwaye ibangele i-powdering.
I-irrational putty powder formula: Ininzi okanye i-HPMC encinci isetyenzisiweyo, kwaye umlinganiselo wezinto ze-cementitious awufanelekanga, okuya kubangela ukunamathela okunganeleyo kunye namandla e-putty powder, ngaloo ndlela kubangele umgubo.
I-powdering phenomenon ye-putty powder ihambelana ngokusondeleyo nokusetyenziswa kwe-HPMC. Umsebenzi oyintloko we-HPMC kwi-putty powder kukugcina amanzi kunye nokuqina. Ukusetyenziswa ngokufanelekileyo kunokuthintela ngokufanelekileyo ukuvela komgubo. Nangona kunjalo, ukuvela komgubo akuxhomekanga kuphela kwi-HPMC, kodwa nakwizinto ezifana nefomula ye-putty powder, unyango lwe-substrate, kunye nendawo yokwakha. Ukuze uthintele ingxaki yomgubo, kukwabalulekile ukuba ukhethe i-HPMC ekumgangatho ophezulu, uyilo lwefomula efanelekileyo, iteknoloji yokwakha yenzululwazi kunye nendawo efanelekileyo yokwakha.
