Iputty powder off ingxaki yomgubo

I-De-powdering kunye nokumhlophe kodonga lwangaphakathi lwe-putty powder okwangoku zezona ngxaki zixhaphakileyo emva kokwakhiwa kwe-putty.Ukuqonda izizathu ze-putty powder de-powdering yangaphakathi, umntu kufuneka aqonde kuqala amacandelo ezinto ezisisiseko kunye nemigaqo yokuphilisa ye-putty yangaphakathi yodonga, kwaye udibanise Ngexesha lokwakhiwa kwe-putty, ukoma komphezulu wodonga, izinga lokufunxa amanzi, ubushushu. , ukoma kwemozulu, njl., Fumana izizathu eziphambili ze-powder drop of putty powder eludongeni lwangaphakathi kwaye usebenzise indlela ehambelanayo yokusombulula ingxaki ye-powder drop of putty powder.

Ubume bemathiriyeli esisiseko yodonga lwangaphakathi lweputty powder:

Ezona zithako zisisiseko somgubo weputty yangaphakathi zibandakanya: imathiriyeli yokubopha i-inorganic (uthuthu lwekhalsiyam), izihluzi (umgubo wekhalsiyam enzima, umgubo wetalcum, njl.njl.) izongezo zepolymer (HPMC, i-polyvinyl alcohol, umgubo werabha, njl.)

Phakathi kwabo, udonga lwangaphakathi lwe-putty powder ngokubanzi alufaki isamente emhlophe okanye yongeza kuphela inani elincinci le-samente emhlophe.I-latex powder enokuphinda isetyenziswe inefuthe elincinci kwimeko yedosi ephantsi, ngoko ke ayisetyenziswanga ngaphakathi eludongeni lwe-putty powder ikakhulu ngenxa yeendleko, okanye ayifane isetyenziswe.

Ke ngenxa yengxaki yodonga lwangaphakathi lwe-putty powder formula ngokwayo:

1. Izinto ezidibanisa i-inorganic, ezifana nokongezwa kwe-ash calcium iphantsi kakhulu, kwaye umgangatho we-ash calcium awukho kumgangatho;

2. Ukuba ubungakanani becandelo lokudibanisa kwi-polymer additive liphantsi kakhulu okanye umgangatho awukho kumgangatho, unokubangela ukuba i-putty powder eludongeni lwangaphakathi iwele.

Yahlulwe ngokwemiba ilandelayo:

01. Amandla okubambelela kwi-putty akwanele ukuba kubangele ukukhutshwa komgubo.Umenzi unciphisa iindleko ngobumfama.Amandla okubambelela kwipowder yerubha ahluphekile kwaye inani lokongezwa lincinci, ngakumbi kwi-putty yangaphakathi yodonga.Umgangatho werabha yerabha kunye neglue inento eninzi yokwenza kunye nemali eyongeziweyo.

02. Ifomula yoyilo ayinangqiqo, ingxaki yokukhethwa kwezinto kunye nesakhiwo kubaluleke kakhulu kwi-putty formula.Ngokomzekelo, i-hydroxypropyl methylcellulose (HPMC) isetyenziswe njenge-putty engenamanzi yodonga lwangaphakathi.Nangona i-HPMC ibiza kakhulu, ayisebenzi kwiifayili ezifana ne-double fly powder, i-talcum powder, i-wollastonite powder, njl. Ukuba kuphela i-HPMC isetyenzisiweyo, iya kubangela i-delamination.Nangona kunjalo, i-CMC kunye ne-CMS enamaxabiso aphantsi ayisusi i-powder, kodwa i-CMC kunye ne-CMS ayinakusetyenziswa njenge-putty engenamanzi, kwaye ayinakusetyenziswa njenge-putty yangaphandle eludongeni, kuba i-CMC kunye ne-CMS isabela nge-gray calcium powder kunye ne-samente emhlophe, eya kubangela delamination.Kukwakho i-polyacrylamides eyongezwe kwi-lime calcium powder kunye nesamente emhlophe njengezinto zokugquma ezingangeni manzi, eziya kubangela ukusabela kweekhemikhali kubangele ukususwa komgubo.

03. Ukuxuba okungafaniyo kunye nokuvuselela isizathu esona sizathu sokukhutshwa kwepowder kwi-putty ngaphakathi kunye neendonga zangaphandle.Abanye abavelisi kweli lizwe bavelisa i-putty powder kunye nezixhobo ezilula kunye nezahlukeneyo.Azikho izixhobo ezikhethekileyo zokuxuba, kwaye ukuxubana ngokungalingani kubangela ukususwa kwe-putty powder.

04. Impazamo kwinkqubo yokuvelisa ibangela ukuba i-putty ibe ngumgubo.Ukuba umxube wokuxuba awunawo umsebenzi wokucoca kwaye kukho iintsalela ezininzi, i-CMC kwi-putty eqhelekileyo iya kusabela nge-ash calcium powder kwi-putty engenamanzi.I-CMC, i-CMS kunye nesamente emhlophe yodonga lwangaphandle lwe-putty iyasabela kwaye ibangele ukukhupha umgubo.Izixhobo ezikhethekileyo zeenkampani ezithile zixhotyiswe ngezibuko lokucoca, ezinokucoca intsalela kumatshini, kungekuphela nje ukuqinisekisa umgangatho we-putty, kodwa nokusebenzisa umatshini omnye ngeenjongo ezininzi, kwaye uthenge isixhobo esinye ukuvelisa iintlobo ezahlukeneyo zezixhobo. iputty.

05. Umgangatho wokuzalisa kwakhona kulula ukubangela i-powdering.Inani elikhulu lokuzalisa lisetyenziswa ngaphakathi nangaphandle eludongeni putty, kodwa umxholo weCa2CO3 kwipowder enzima ye-calcium kunye ne-talc powder kwiindawo ezahlukeneyo wahlukile, kwaye umahluko kwi-pH uya kubangela ukubola kwe-putty, njengeChongqing kunye Udonga lwangaphakathi lwe-Chengdu lusebenzisa umgubo werabha ofanayo, kodwa umgubo wetalcum kunye nomgubo wekhalsiyam onzima zahlukile.Ayiwohlisi umgubo eChongqing, kodwa yenza umgubo eChengdu.Ayiwohlisi umgubo eHenan nakuMntla-mpuma weTshayina, kodwa iyawuphelisa umgubo kwezinye iindawo.

06. Isizathu semozulu sisizathu sokukhutshwa komgubo we-putty kwiindonga zangaphakathi nangaphandle.Ngokomzekelo, i-putty kwiindonga zangaphakathi nangaphandle zinemozulu eyomileyo kunye nomoya omhle kwiindawo ezomileyo ezisenyakatho.Ezinye iindawo zinemozulu yemvula, umswakama wexesha elide, i-putty film-forming properties ayilungile, kwaye iya kulahlekelwa ngumgubo, ngoko ke ezinye iindawo zifanelekile kwi-putty engenamanzi kunye ne-ash calcium powder.

07. Izibophelelo ze-inorganic ezifana ne-gray calcium powder kunye ne-samente emhlophe zingcolile kwaye ziqulethe inani elikhulu le-Shuangfei powder.Into ebizwa ngokuba yi-multi-functional grey powder ye-calcium kunye ne-samente emhlophe enemisebenzi emininzi kwimarike ayicocekanga, kuba isixa esikhulu sezi zibophelelo ze-inorganic zisetyenziswa, kwaye i-putty engenamanzi kwiindonga zangaphakathi nangaphandle ngokuqinisekileyo ziya kuba zingenamgubo. kwaye hayi amanzi.

08. Ehlotyeni, ukugcinwa kwamanzi kwi-putty eludongeni lwangaphandle akwanele, ngakumbi kwiindawo ezinobushushu obuphezulu kunye neendawo ezinomoya ezifana neminyango ephezulu kunye neefestile.Ixesha lokuqala lokumisela i-ash calcium powder kunye ne-samente ayanele, kwaye amanzi aya kulahleka.Ukuba ayigcinwanga kakuhle, iya kuba ngumgubo kakhulu .
