Ukudweba kwePolymer: izinhlobo nezinhloso

Ukupenda kwe-polymer kuyinkomba eyenziwa yi- non-waste technology. Lezi zinhlanganisela zinobuhle bemvelo, futhi zakhiwa ezivela powmer powder, ezisetshenziswa ezindaweni ezidwetshiwe zemikhiqizo ehlukene. Uma ukugqoka kwenziwa efektri, emva kokuphathwa kokwelapha noma umkhiqizo odweba i-polymeri, i-substrate iyashisa futhi igcinwe ekushiseni okuthile kwemaminithi amaningana.

Izici Eziyinhloko

Ukupenda kwe-Polymer kunezinzuzo eziningi, kubiza kancane, ngoba ayinayo izixazululo, ezakhiweni zamakhemikhali ezidlala indima yabathwali ekufakwe ifilimu. Isikhathi sokuqinisa izingoma ezinjalo sincishisiwe, ngoba ukwakheka kwefilimu kwenzeka ngesivinini esikhulu. Isigqoko singenziwa ohlangothini owodwa, okuhlukanisa lokwakheka kusuka kumapulatifomu avamile, okudinga isidingo sohlelo olubanzi lwezingqimba ngokumiswa okuphindaphindiwe.

Esikhathini somsebenzi, imisebenzi enzima kangaka njengendlela yokuhleleka kahle kwepharamitha ye-viscosity kanye nokulawulwa kwaleli xabiso akufakiwe. Izingoma zomlilo zihlinzekwa ngomumo, okuqinisekisa ukulula kwabo kwesicelo. Ngemuva kokuzijwayeza nge-assortment yemikhiqizo enjalo, ungakhetha eyodwa yemibala engu-5000, ukuthungwa nama-shades. Emva kokusebenzisa ukubunjwa, imishini yokuhlanza ingahlanzwa kalula, ngoba kulula kakhulu ukususa i-powder kunezingqimba eziningi zokupenda okwegazi.

Ukupenda kwe-polymer kudala uhlaka olulodwa olulodwa, oluvuthayo olukuvumela ukuba ulondoloze ngenxa yokuqukethwe kwendaba ka-100% eyomile. Uma isetshenziswa ngaphansi kwengcindezi, izingxube ze-powder zilahlekelwa ngu-4% ngokwevolumu, lokhu kuyinzuzo ngaphezu kwezinto zoketshezi zamanzi, ezilahlekelwa ngu-40%. Izembatho ezitholakalayo zinezici ezinhle kakhulu zomzimba, futhi ubuso bubonakala ngokuzinza kwamakhemikhali.

Izinhlobo eziyisisekelo zamaphoyinti we-polymer

Uma unesithakazelo ekupendekeni kwe-polymeri, kufanele uzijwayele ngokuhambisana nalokhu mkhiqizo. Izinto ezinjalo kungaba polyester, epoxy, polyurethane noma epoxy-polyester. Njengoba inzuzo enkulu yamapayipi epoxy kuyinhlanganisela enhle kakhulu yezimpawu zokuzivikela zomzimba nezokugesi. Ukugqoka okunjalo kunamathele kakhulu, okuphawuleka ukuqina kwamakhemikhali namandla omzimba. Izisekelo zithinta ama-acids nama-alkali, uphethiloli, amafutha, amanzi, okuvumela ukusetshenziswa kwe-epoxy compound ukuvikelwa kwangaphakathi nangaphandle kwamapayipi amakhulu.

Uma uhlela ukusebenzisa amapayipi e-epoxy resin, ungakha ungqimba ngobukhulu obufinyelela ku-500 μm. Ngesikhathi esifanayo, ubulukhuni obuhle, amandla omthelela ophezulu kanye nokuqina kwezinto ezibonakalayo kuzobanjwa yonke indawo. Kodwa-ke, kunezimo ezimbi zokugqoka, ezichazwe ekuncintweni okulinganiselwe kwezulu. Ezindaweni ezivulekile, kungenzeka kube nokushaywa nokuthambekela kokuphuza, okungenxa yokushisa.

Indawo yokusetshenziswa kwamapayipi e-epoxy resin

I-Epoxy polymer powder powder isetshenziselwa ukugqoka okunamandla okumelana namakhemikhali nama-solvents. Abathengi be-powders elinjalo yizinkambu zobunjiniyela bomsakazo kanye nobunjiniyela bamagesi, kulezi zindawo ukugqoka kuthathelwa izinhlobo eziningi zokuxilonga kagesi okuyinkimbinkimbi. Ukumboza nge-epoxy compound kungaba amakhandishi kagesi, ukufakwa kwehhovisi, imishini yezokwelapha kanye nezinto zokusebenza zasendlini.

Indawo yokusetshenziswa kwamaphoyinti e-polyester polymer

Amakhemikhali afanayo asetshenziselwa ukuqedela izinto zasendlini, ingadi, yezokwelapha, zensimbi, ifenisha yehhovisi, imishini yezemidlalo, nemishini kagesi, njll. Polyethers iyadingeka kakhulu ngenxa yezimfanelo zabo eziyingqayizivele zokuhlobisa. Ubuchwepheshe banamuhla bokukhiqizwa kwamapayipi e-powder bavunyelwe ukwandisa ububanzi bombala wezingubo futhi bafeze ukuthungwa okuhlukile.

Izindawo zokusetshenziswa kwepolyester ne-polyurethane amapolisi

Ukupenda kwe-polyester yezingubo ze- polymer isetshenziselwa ukucubungula izesekeli zokuhamba, imishini yezolimo, amasondo emoto, kanye ne-aluminium kanye namaphrofayli ensimbi wokuvuleka komnyango nezindwangu. Amakhemikhali e-polyester ayonke, njengoba angasetshenziselwa ukusetshenziswa kwangaphakathi nangaphandle. Ngenxa yalokho, kungenzeka ukuthola indawo ecacile, ukukhanya okufinyelela ku-90%. Ngaphandle kwalokho, ingxube ye-polyester ingasetshenziswa evumela ukubunjwa kwesimo sematt noma semi-matt.

I-polyurethane yabekwa phezu kwe-polymer base ihlukaniswa ngogesi olumisiwe, olubhekene nokumelana kwamanzi nesimo sezulu. Zihamba kahle ngaphansi kwethonya lamaminerali amaminerali, amafutha kanye nama-solvents. Amapayipi e-polyurethane asetshenziselwa ukuvikela imikhiqizo ekhonjelwe ukuhlukunyezwa nokuxubana. Ukusebenza kwabo kungenziwa kwezinye izinhlobo zemishini yamakhemikhali namathangi, eklanyelwe ukugcina amakhemikhali amancane negesi. Kungenzeka ukusebenzisa amapayipi e-polyurethane njenge-primer ngaphambi kokusebenzisa amanye amapayipi e-powder, ngokwesibonelo, amapayipi e-polyacrylic noma epoxy.

Inhloso yepeyinti ye-polymer yensimbi

Ukupenda kwe- Polymer yensimbi kunesisombululo, izithasiselo ezikhethekile, i-polystyrene, kanye ne-pigment. Le nhlanganisela ibizwa ngokuthi i-plastic plastic futhi iyisixazululo se-polystyrene echotshoziwe ku-solvent noma toluene. Uma sicabangela ukwakheka kwe-polymer yensimbi, umuntu angasho njengesibonelo PS-160. Le nhlanganisela isetshenziselwa ukwelashwa kwamapayipi, ukuvikelwa kwezakhiwo zensimbi zamachibi, ukumboza izitshalo zensimbi, kanye nokudweba izakhi ezithwala imithwalo yezakhiwo. Ngokuphathelene namapayipi, lapha kuyadingeka ukuthi ufake ama-heat mains. Izisekelo zensimbi zingafakwa emikhumbi, ngaphakathi kwemikhiqizo yokukhiqiza nezokugcina. Umdwebo onjalo wepolitiki ungavikela izindawo ezihlale zixhumana namanzi.

Inhloso kanye nezakhiwo zezingxenye ze-polymer ze-acrylic

Amapulangwe e-polymer acrylic angasetshenziselwa umsebenzi wangaphakathi nangaphandle emkhakheni wezingqimba, kanye nokwakhiwa nokudweba kokuthungwa kwensimbi. Ngaphambi kokusebenzisa lokhu kwakheka, kunconywa ukuthi usebenzise i-primer. Phakathi kwezici zalezi zingxube zingase zihlukaniswe ukuxhaphazwa kwesikhathi eside, okufinyelela eminyakeni engu-20. Akunakwenzeka ukuba ungasho ukuthi kungenzeka ukuthi uthola ukugqoka okuhlala njalo futhi okuhlala njalo, ukumelana okuhle nomswakama ophezulu, izinguquko zokushisa nokushisa elangeni. Ngaphezu kwalokho, la mapende ayenamandla okushisa nokushisa kwamaqhwa. Ngemuva kwesicelo phezulu, bayomisa ngokushesha ngokwanele ukwakha ifilimu encane, ebushelelezi futhi eqinile kakhulu evikelayo. Ngenkathi yokusebenza, iveza izimfanelo zokumelana nemiphumela yamakhemikhali kanye nokuxuba okuhlukahlukene kwe-detergent. Ukusebenzisa ukudweba kwama-acrylic kulula, akudingi ukusetshenziswa kwemishini ebiza kakhulu. Izingoma ze-polymer ze-Acrylic zinamathele aphezulu e-substrate, zingumngane futhi zingenabungozi empilweni yabantu.

I-Polyurethane ipende ye-polymer yekhonkrithi

Lo mbala usebenza njengezinzile kunazo zonke ngaphambi kokuthonya kwezinto ezimbi. Ukushona akuwona imikhiqizo emibi yamafutha, ama-chemical and solvents. Ngenxa yalesi sici, ukudweba kwe-polyurethane kungasetshenziselwa ukudweba amagaraji, ama-hangars, izakhiwo zezimboni kanye nezisetshenziswa. Ubuso ngemuva kokugqoka nalo mkhiqizo luzuza izinga lokuvikelwa ekuthusweni nasekulimaleni kwemishini. Ubungqimba bungaba yi-glossy noma i-matte, futhi imitha eyodwa yesikwele uzoyisebenzisa cishe ngo-400 g. Ngaphambi kokuqala umdwebo, ubuso buphathwa nge-primer, futhi ngemuva kokupenda kwe-polyurethane kufakwe emigqeni emibili. Owesibini wabo kufanele usetshenziswe kuphela emva kokuba owokuqala ome ngokuphelele, okuzokwenzeka cishe ngosuku oluzayo.

Isiphetho

Phakathi kwamabala we-polymer ungathola yonke indawo, epoxy, engasetshenziselwa imisebenzi yangaphakathi nangaphandle. Ngaphezu kwalokho, le teyinti yukuthi iyakwazi ukufaka esikhundleni se-primer, ikuvumela ukuthi ulondoloze.
