1. Yiziphi izithako kufomula ye-putty odongeni?
Ukwakhiwa kwe-wall putty kuhlanganisa ama-adhesives, ama-fillers kanye nezithasiselo.
Ireferensi yeresiphi ye-putty yangaphandle
Isisindo (kg) Impahla
300 Usimende wobumba omhlophe noma ompunga 42.5
220 i-silica powder (160-200 mesh)
450 i-calcium powder esindayo (0.045mm)
6-10 Redispersible polymer powder (RDP) ET3080
4.5-5 HPMC MP45000 noma HEMC ME45000
3 i-white wood fiber
1 i-polypropylene fiber (ubukhulu obuyi-3 mm)
I-wall putty ihlanganisa i-wall putty yangaphakathi kanye ne-wall putty yangaphandle. Umsebenzi wayo oyinhloko ukulungisa ukungalingani nokwenza udonga lube bushelelezi.
1.1 Ingcina
Okuhlanganisayo kufomula ye-putty odongeni kusimende, impushana ye-polymer ene-viscosity ephezulu, kanye ne-lime e-slaked. Usimende usetshenziswa kakhulu ekwakheni. Idume ngokunamathela kwayo okuhle, ubulukhuni obuphezulu kanye nokusebenza kwezindleko eziphezulu. Kodwa amandla aqinile kanye nokumelana nokuqhekeka kuncane. I-Powder powder iyimpushana ye-polymer ehlakazeka kabusha. Ingadlala indima yokubopha kumafomula we-putty odongeni.
1.2 Ukugcwalisa
Izihlungi kufomula ye-putty odongeni zibhekisela ku-calcium carbonate esindayo, i-Shuangfei powder, impushana ye-calcium empunga, ne-talc powder. Ukucoleka kokugaya i-calcium carbonate cishe kungama-mesh angama-200. Ungasebenzisi izihlungi eziyimbudumbudu kakhulu kufomula yakho ye-putty odongeni. Lokhu kubangela ukucaba okungalingani. Ukuqina kuyisici esibalulekile ekwakhiweni kwe-wall putty. Ubumba be-Bentonite ngezinye izikhathi lwengezwa ukwandisa ukubamba.
1.3 Izinsizakusebenza
Izithasiselo kumafomula we-putty odongeni zihlanganisa ama-cellulose ether kanye ne-VAE redispersible latex powder. Lolu hlobo lwesithasiselo ludlala indima yokuqina nokugcinwa kwamanzi. Ama-ether e-cellulose amakhulu yi-HPMC, i-MHEC, ne-CMC. Inani le-cellulose ether elisetshenzisiwe libalulekile ekwakhekeni okusebenzayo.
I-Hydroxypropylmethylcellulose
Esakhiweni se-HPMC, ikhemikhali eyodwa i-hydroxypropionyl. Ukuphakama kweqembu le-hydroxypropoxy, kuba ngcono umphumela wokugcina amanzi. Enye ikhemikhali i-methoxy. Ukushisa kwejeli kuncike kuyo. Ezindaweni ezishisayo, abasebenzi banake kakhulu le nkomba. Ngoba uma izinga lokushisa le-ambient lidlula izinga lokushisa lejeli le-HPMC, i-cellulose izophuma emanzini futhi ilahlekelwe ukugcinwa kwayo kwamanzi. Ku-MHEC, izinga lokushisa lejeli liphakeme kunalelo le-HPMC. Ngakho-ke, i-MHEC inokugcinwa kwamanzi okungcono.
I-HPMC ayihlanganisi amakhemikhali. Inokugcinwa kahle kwamanzi, ukujiya kanye nokusebenza kahle.
1. Ukungaguquguquki: I-cellulose ether ingajiya futhi igcine umfaniswano wekhambi phezulu naphansi. Inikeza i-wall putty ukumelana ne-sag enhle.
2. Ukugcinwa kwamanzi: Yehlisa isivinini sokumisa se-putty powder. Futhi kunenzuzo ekuphenduleni kwamakhemikhali phakathi kwe-gray calcium namanzi.
3. Ukusebenza kahle: i-cellulose ether inomsebenzi wokugcoba. Lokhu kunganikeza i-wall putty ukusebenza kahle.
I-polymer powder ehlakazeka kabusha ibhekisela ku-VAE RDP. Umthamo wayo uphansi. Ezinye izisebenzi zingase zingayengezi kufomula ye-putty odongeni ukuze wonge imali. I-RDP ingenza i-wall putty ibe lula, ingangeni manzi futhi ibe nezimo. Ukwengezwa kwempushana ye-polymer ehlakazeka kabusha kusheshisa ukusetshenziswa futhi kuthuthukisa ukushelela.

Ngezinye izikhathi, izindlela zokupheka ze-wall putty ziqukethe imicu, njengemicu ye-polypropylene noma imicu yokhuni. Ikhonkrithi ye-PP fiber iyindlela ephumelelayo yokuvimbela imifantu.
polypropylene fiber ukhonkolo
Amacebiso: 1. Nakuba i-cellulose ether iyisici esibalulekile kufomula ye-putty powder. Kodwa-ke, umthamo we-cellulose ether kufanele futhi ulawulwe ngokuqinile. Lokhu kungenxa yokuthi ama-cellulose ethers, njenge-HPMC, angenziwa emulsified. Uma isetshenziswe ngokweqile, ama-cellulose ether angahlanganisa futhi afake umoya. Ngalesi sikhathi, i-putty izomunca amanzi amaningi nomoya. Ngemva kokuhwamuka kwamanzi, ungqimba lwe-putty lushiya isikhala esikhulu. Lokhu kuzogcina kuholele ekwehleni kwamandla.
2. I-powder yerabha kuphela yengezwe ku-putty odongeni ifomula, futhi akukho cellulose engeziwe, okuzokwenza ukuthi i-putty ibe yimpuphu.
2. Izinhlobo ze-wall putty
I-HPMC wall putty esetshenziselwa i-wall putty ihlanganisa i-wall putty yangaphakathi kanye ne-wall putty yangaphandle. I-wall putty yangaphandle izophazanyiswa umoya, isihlabathi, nesimo sezulu esishisayo. Ngakho-ke, iqukethe ama-polymers amaningi futhi inamandla aphezulu. Kodwa inkomba yayo yezemvelo iphansi. Kodwa-ke, izinkomba eziphelele ze-wall putty yangaphakathi zingcono. Ifomula ye-putty yodonga lwangaphakathi ayinazo izinto eziyingozi.
Amafomula we-wall putty ikakhulukazi ahlanganisa i-gypsum-based wall putty kanye ne-samente-based wall putty. Lawa mafomula ahlangana kalula nezisekelo. Kukhona iresiphi ye-wall putty kanje:
2.1 Ifomula ye-putty esekelwe kusimende omhlophe odongeni
I-wall putty esekelwe kusimende emhlophe ingasetshenziswa ezindongeni zangaphakathi nezangaphandle. Zombili izindonga ezimpunga nezikhonkolo zingayisebenzisa. Lolu hlobo lwe-putty lusebenzisa usimende omhlophe njengento eyinhloko. Bese kwengezwa ama-fillers nezithasiselo. Ngemuva kokumisa, akukho phunga elibi elizokhiqizwa. Ifomula esekwe kusimende inikeza amandla aphezulu nobulukhuni.
2.2 Ifomula ye-Acrylic wall putty
I-Acrylic putty i-adhesive ye-acrylic eyenziwe ngezinto ezikhethekile. Inokuqina okufana nebhotela lamantongomane. Ingasetshenziselwa ukugcwalisa imifantu kanye nezimbobo zokuvala ezindongeni
Uyini umehluko phakathi kwe-putty yodonga olusekelwe kusimende ne-acrylic wall putty?
I-Acrylic putty ifaneleka ezindongeni zangaphakathi, kodwa ibiza ngaphezu kwe-putty esekwe usimende. Ukumelana kwayo ne-alkali nobumhlophe nakho kungcono kune-putty esekwe kusimende. Ngaphezu kwalokho, yoma ngokushesha kunosimende omhlophe, ngakho-ke umsebenzi udinga ukwenziwa ngokushesha.
2.3 Ifomula ye-putty yodonga eguquguqukayo
I-Flexible putty iqukethe usimende wekhwalithi ephezulu, izigcwalisi, ama-polymer okwenziwa kanye nezithasiselo. Futhi ukukhanya kwelanga ngeke kuthinte ukwakhiwa kwe-putty. I-Flexible putty inamandla okubopha okuphezulu, indawo eyisicaba futhi ebushelelezi, futhi ivikela amanzi kanye nomswakama.
Ngokufigqiwe
Lapho ukhetha ifomula ye-putty efanele, ngokuvamile akunakwenzeka ukukhuluma ngefomula yokuqala. Ifomula kufanele ihlanganiswe nendawo ezungezile, efana nezici zesifunda, ikhwalithi yezinto ezingavuthiwe… Ifomula ye-putty ephelele kakhulu ukusebenzisa i-putty ngokwezimo zendawo. Shintsha ifomula ye-putty ukuze uthole umphumela wokukhuhla.
