Kukho ubudlelwane obuthile phakathi komgangatho wepowder we-putty powder kunye ne-HPMC (i-hydroxypropyl methylcellulose), kodwa imisebenzi kunye nemiphumo yezi zibini zihluke.
1. Ukuqulunqwa kunye neempawu zomgubo weputty powder
I-Putty powder sisixhobo sokwakha esisetyenziselwa ukulinganisa udonga, ukulungiswa kunye nokuhombisa. Amacandelo aphambili aquka izinto ezisisiseko (ezifana ne-samente, i-gypsum), iifayili (ezifana ne-calcium carbonate) kunye nezongezo (ezifana ne-cellulose ether, i-agent yokugcina amanzi, njl.). Umgangatho wepowder we-putty ubhekisela ikakhulu kubuhle, ukufana kunye nokuvakalelwa kwamaqhekeza awo ngexesha lokwakhiwa. Lo mgangatho womgubo uchatshazelwa zezi zinto zilandelayo:
I-particle size of filler: I-Calcium carbonate idla ngokusetyenziswa njengeyona nto iphambili yokuzalisa. I-calcium carbonate particles icolekileyo, iphucula umgangatho womgubo we-putty powder, kwaye ingcono i-flatness kunye nokuguda kodonga emva kokufakwa kwesicelo.
Uhlobo lwezinto ezisisiseko: Ngokomzekelo, i-sement-based putty powder kunye ne-gypsum-based putty powder iya kuba nemvakalelo eyahlukileyo kunye neempawu ngenxa yezixhobo ezahlukeneyo ezisetyenzisiweyo. Amasuntswana e-samente-based putty powder anokuba rhabaxa, ngelixa ezo ze-gypsum-based putty powder zinokuba ngcono.
Iteknoloji yokucubungula: Kwinkqubo yokuvelisa i-putty powder, iqondo lokugaya kunye nokufana kwefomula kuya kuchaphazela umgangatho we powder. Itekhnoloji yokulungisa ngcono inokuvelisa umgubo othambileyo kunye nofana ngokufanayo.
2. Indima ye-HPMC kwi-putty powder
I-HPMC, ebizwa ngokuba yi-hydroxypropyl methylcellulose, iyongezo eqhelekileyo kwi-putty powder. Yipolymer enyibilikayo emanzini edlala indima enkulu yokuqina, ukugcinwa kwamanzi kunye nokuphucula ukusebenza kolwakhiwo. I-HPMC ngokwayo ayichaphazeli ngokuthe ngqo i-particle fineness (okt umgangatho we-powder) we-putty powder, kodwa inempembelelo ebalulekileyo yokuphucula ukwakhiwa kwe-putty powder:
Umphumo wokugcinwa kwamanzi: Umsebenzi obalulekileyo we-HPMC kukugcinwa kwamanzi, okunokulibazisa ukukhuphuka kwamanzi kwi-putty powder ngexesha lokwakhiwa kunye nokukhusela i-putty powder ukuba yome ngaphambi kwexesha ngexesha lokwakhiwa kodonga. Oku kunefuthe elihle ekulinganisweni kodonga kunye nokubambelela, ngokukodwa kwiqondo lokushisa eliphezulu kunye nokusingqongileyo okomileyo, ukugcinwa kwamanzi kubaluleke kakhulu.
I-Thickening effect: I-HPMC inokunyusa i-viscosity ye-putty powder, ukwenzela ukuba ibe nokuhambelana okuphakathi kunye nokukrala okulula emva kokuvuselela. Esi siphumo sinceda ukulawula umbane we-putty powder ngexesha lokwakha, kunciphisa isiganeko sokubhabha kunye nomgubo wokuwa, kwaye unokunyusa amandla okudibanisa, ngaloo ndlela uphucula ngokungathanga ngqo ukuvakalelwa ngexesha lokwakha.
Ukuphucula ukusebenza kolwakhiwo: Ubukho be-HPMC bunokwenza i-putty powder ibe lula ukusebenza ngexesha lokwakha, uzive ugudile, kwaye ubonise umphumo ofanayo kunye nobuthathaka xa ulula. Nangona i-HPMC ingatshintshi i-fineness ye-putty powder particles, iphucula ukusebenza okubanzi kokusebenza kwaye yenza ukuvakalelwa kwepowder ibe buthathaka ngakumbi xa isetyenziswa.
3. Impembelelo engathanga ngqo ye-HPMC kumgangatho we-putty powder
Nangona i-HPMC ingatshintshi ngokuthe ngqo ubungakanani be-particle okanye i-fineness ye-putty powder, iphucula umphumo wokwakhiwa kwe-putty powder ngokugcinwa kwamanzi, ukuqina, i-lubricity kunye neminye imiba, okwenza i-putty powder ibe lula kwaye kulula ukuyisebenzisa xa isetyenziswa. Ngexesha lenkqubo yokwakha, i-putty powder equkethe i-HPMC kulula ukuyisebenzisa i-flat, ukunciphisa imikrwelo kunye nokungalingani, okwenza abasebenzisi bazive ngathi i-powder ithambile.
Ukugcinwa kwamanzi kwe-HPMC kunokuthintela ukuqhekeka kwe-shrinkage kwi-putty powder ngexesha lokumisa udonga, olunempembelelo entle ekuphuculeni ukugcwala okupheleleyo kunye nokugudiswa kodonga. Ngoko ke, ngokombono wesiphumo sokugqibela sodonga, i-HPMC inefuthe elithile elingathanga ngqo kwi-fineness ye-putty powder.
4. Ubudlelwane phakathi kwedosi ye-HPMC kunye nomgangatho we powder
Idosi ye-HPMC nayo ifuna ukulawulwa ngokufanelekileyo. Ngokuqhelekileyo, idosi ye-HPMC kwi-putty powder incinci, kwaye ukusetyenziswa ngokugqithiseleyo kuya kukhokelela kwezi ngxaki zilandelayo:
Ukugqithisa ngokugqithiseleyo: Ukuba i-dosage ye-HPMC ininzi kakhulu, i-putty powder ingaba yi-viscous kakhulu, yenza kube nzima ukuvuselela, kwaye inokubangela iingxaki ezifana nokulahlekelwa ngumgubo kunye nokunamathela kwendawo. Akulula ukusebenzisa i-flat ngexesha lokwakhiwa, okuya kuchaphazela umphumo wokugqibela wodonga kwaye unike abantu imvakalelo yomgubo orhabaxa.
Ukwandisa ixesha lokumisa: Isiphumo sokugcinwa kwamanzi se-HPMC siya kulibazisa ixesha lokumisa i-putty powder. Ukuba i-dosage ininzi kakhulu, udonga alukwazi ukomisa ixesha elide, olungenakulungelelaniswa nenkqubela phambili yokwakha.
Ngoko ke, i-dosage ye-HPMC kufuneka ibe phakathi koluhlu olufanelekileyo lokudlala indima yalo ekuphuculeni umgangatho we-putty powder.
Umgangatho we-putty powder unqunywe ngokukodwa ngokucokisekileyo kwesiseko sayo kunye nokuzalisa, kunye nenkqubo yokuvelisa kunye nezinye izinto. Njengokongeza kwi-putty powder, i-HPMC ayigxininisi ngokuthe ngqo umgangatho womgubo, kodwa inempembelelo engathanga ngqo kwi-fineness yomgangatho wayo womgubo ngokuphucula ukugcinwa kwamanzi, ukuqina kunye nezakhiwo zokwakha ze-putty powder. Ukusetyenziswa okunengqiqo kwe-HPMC kunokwenza i-putty powder ibonise ukuvakalelwa ngcono kunye nesiphumo sesicelo ngexesha lokwakha, ukunciphisa iziphene zokwakha, kwaye ngaloo ndlela kuphuculwe ukucaca okupheleleyo kunye nokucoleka kodonga.
