Ukusetyenziswa kwe-wax ye-polyethylene kwi-powder coatings

Polyethylene waxluhlobo lwemathiriyeli yeekhemikhali, apho umbala we-wax ye-polyethylene ngamaso amancinci amancinci / ama-flakes, eyenziwa yi-ethylene polymerized agent processing rubber.Uneempawu zeqondo eliphezulu lokunyibilika, ubunzima obuphezulu, i-gloss ephezulu kunye nombala omhlophe wekhephu.Inokunyibilika kwi-104-130 ℃ okanye inyibilike kwi-solvent kunye ne-resin kwiqondo lobushushu obuphezulu, kodwa iya kunyuka xa ipholisa.Ukucocwa kwayo kwemvula kuhambelana nezinga lokupholisa: iinqununu ezinqabileyo (5-10um) zifunyenwe ngokupholisa ngokukhawuleza, kunye neengqungquthela ezicolekileyo (1.5-3um) zihlanjululwa ngokupholisa ngokukhawuleza, Kwinkqubo yokwenza ifilimu yokugubungela umgubo, xa ifilimu. pholile,pe wax i-precipitates ukusuka kwisisombululo sokugquma ukwenza iincinci ezintle, ezidada phezu kwefilimu kwaye zinokudlala indima yokuthungwa, ukucima, ukuguda kunye nokuchasana nokuqala.Iipateni ezahlukeneyo zinokufunyanwa ngokukhetha ngokufanelekileyo i-wax yomgubo omncinci kunye nenkqubo yokwambathisa.

1. Isiphumo se-polyethylene wax:
(1) Ukuthungwa kunye nokucima: xa ifilimu yokugubungela ipholile, i-wax ye-polyethylene iyancipha kwi-coating kwaye ifudukela kumphezulu wefilimu yokugubungela ukuvelisa iphethini kunye nomphumo wokucima;Kwiingubo zomgubo, i-wax ezahlukeneyo zinciphisa i-gloss ngokwahlukileyo.Iiwax zinokukhethwa ngokweemfuno zeglosi.Ukongezwa kwe-polyethylene wax yi-1%, i-60, kwaye i-gloss iyancipha ngo-5-15.
(2) Ukumelana nokukrazula, ukumelana nokunxiba, ukuchasana nokupolisha kunye nokumelana nokukrola: i-polyethylene wax enamaqhosha amancinci ikhona kwindawo yokugquma ngendlela yamasuntswana ahlakazekileyo.Nciphisa i-coefficient ye-friction ye-coefficient ye-coefficient, ukwenzela ukuba xa into ingqubuzana ne-coeling surface, ukuthambekela kokutyibilika kukhulu kunotyekelo lokukrala, ukunciphisa ukuthambekela kokupolisha ngenxa yokukhuhlana, kunye nokugcina ukuqina kweglosi ephantsi.Ukongezwa kwe-0.5-1% kunokunciphisa i-coefficient ye-friction eguquguqukayo yefilimu ukusuka kwi-0.35 ukuya kwi-0.25.Xa ezinye izinto ziqhagamshelana neemveliso ezigqunyiweyo, ngamanye amaxesha zishiya amanqaku amnyama kwifilimu.Ukongeza i-wax ye-polyethylene kwifilimu inokunciphisa lo mkhwa okanye wenze amanqaku alula ukuwasula.
3Ukongezwa kwe-0.5-3% kunokunyusa amandla ombala we-pigment nge-10-30%,
(4) Impembelelo kwimveliso ye-extrusion: i-polyethylene wax iyanciphisa i-screw torque, kwaye ukongeza i-1% kunokunyusa isivuno se-extruder nge-5-25%.
(5) Ukuguquguquka kunye nokuthungwa: i-polyethylene wax inika ifilimu ukuthungwa okugqwesileyo.
(6) Ukungangeni manzi: ifilimu ye-waxy ine-hydrophobicity engcono.

2. Umthamo kunye nendlela yokongeza: i-dosage jikelele ye-wax ye-polyethylene yi-1-3%, eyongezwa ngokubanzi ngaphambi kokuba i-extrusion;Inokongezwa ngaphambi nangemva kwe-extrusion, kwaye umphumo obalaseleyo unokufumaneka xa isixa sokongeza isithuba singaphantsi kwe-1%.
3. Izinto ezahlukeneyo
(1) Ubunzima bemolekyuli ephantsi ye-polyethylene homopolymer wax inesiphumo esihle sokuphela kunye neempawu ezibanzi;
(2) I-acyl modified wax yandisa ukungahambelani kunye nokudideka kumacandelo okugubungela.Kwimeko eshushu-encibilikayo, i-viscosity kunye noxinzelelo lomphezulu wenkqubo iyancipha ngokukhawuleza kwaye isiseko se-wax sifudukela kwindawo yokugubungela.Ngenxa yoko, ifilimu edibeneyo yokugquma yenziwa phezu kobuso bengubo emva kokunyanga, okukhokelela ekulahlekelweni kwegloss.Isebenza ngaphandle komgubo we-epoxy resin.
(3) I-Polyoxyethylene i-wax eguquliweyo ye-polyethylene inokuxhathisa okulungileyo kwi-friction, ukumelana nokukhuhla okuphezulu, ukuguda kunye nokuthungwa.I-wax powder iqulethe i-Teflon wax.Ngenxa yokuba ayinakunyibilika, igxininisa phezu komhlaba kunye neqhekeza elilodwa, ibe ngumgca wokuqala wokukhusela ngokuchasene nokugqoka kunye nokwandisa ixesha elingenakunqandwa ukusuka phezulu.Xa ifilimu ipholile, i-wax ye-polyethylene iyancipha ukusuka kulwelo lokugquma ukwenza amasuntswana amahle, adada kumphezulu wefilimu, edlala indima yokuguda kunye nokuchasana nokukrala, ibe ngumgca wesibini wokuzikhusela ekunxibeni.Eyona ndibaniselwano yeTeflon kunye nepolyethylene, Zombini zineenzuzo zeentlobo ezimbini ze-wax powder, kwaye umphumo wokuqina ungcono kakhulu.
