Iingxaki zomgangatho oqhelekileyo kunye neendlela zokuchongwa kwe-latex powder ephinda ihlakazwe

Ngophuhliso olukhawulezayo lwemarike yokonga umbane kwisakhiwo sasekhaya, ngakumbi nangakumbi i-R&D kunye neenkampani zemveliso ziye zangena kwi-R&D kunye nokuveliswa kweemveliso zomgubo wepolymer, kwaye abasebenzisi banendawo yokuzikhethela, kodwa kwangaxeshanye, umgangatho womgubo wepolymer onokuphinda uhlakazwe uye ungalingani. , intlanzi edibeneyo kunye needragons. Ukuze kuncitshiswe iindleko, abanye abavelisi bayayigatya imigangatho yomgangatho, i-shoddy njengemihle, kwaye abanye bade basebenzise i-resin powders eqhelekileyo njenge-latex powders ekwazi ukuphinda ithengiselwe ngamaxabiso aphantsi phantsi kwengubo yomgubo we-latex odispersible, ongaphazamisi imarike kuphela kodwa kwakhona. ukhohlisa umthengi. Kodwa kuqoqosho lwemarike apho abona bafanelekileyo baphila, umgangatho ngumthombo wophuhliso oluzinzileyo, kwaye akukho ngubo yohanahaniso inokuwugubungela. Ngelizwi nje: umgangatho ngumgangatho wexabiso, uphawu luphawu lomgangatho, kwaye imarike ngowona mgangatho wovavanyo lokugqibela.

◆Okokuqala, makhe sihlalutye iingxaki zomgangatho oqhelekileyo we-latex powder edispersible, kunye neendlela eziqhelekileyo kunye nokulimala kwabavelisi abangathembekanga ukunciphisa iindleko:

◆ Indlela yokwahlula okanye ukuchonga umgangatho we-latex powder ohlaziywayo? Ukufumana indlela, qala ngokuhlalutya:

1. Uhlalutyo lwezalathi zemveliso

Izalathisi zisisiseko sokulinganisa umgangatho we-latex powder odispersible. Isalathiso esisemgangathweni yimbonakaliso yamanani yokusebenza okusisiseko kwepolymer powder edispersible. Ukuba uluhlu lwesalathiso sepolymer powder oludispersible ludlula okanye aluphumeleli ukuhlangabezana nomgangatho, luya kuba nefuthe elithe ngqo ekusebenzeni kwalo. Ezona zizathu ziphambili zezalathisi ezingaqhelekanga ziingxaki zemveliso, njengetekhnoloji yokuvelisa ngasemva, izixhobo eziphelelwe lixesha okanye ezigugayo, ukusetyenziswa kwezixhobo ezingabizi kakhulu nezingaphantsi, kunye nokuhlolwa kwemveliso ecolekileyo kwimveliso egqityiweyo. Ngaphezu koko, abanye abavelisi banethuba lokunciphisa iindleko, kungakhathaliseki ukuba semgangathweni, kwaye baswele. Ngoko ke, kuyimfuneko ukukhetha umenzi oqhelekileyo kunye nothembekileyo.

2. Uhlalutyo olusisiseko lokusebenza

1. I-Redispersibility: i-latex powder ene-redispersibility enhle inokuchithwa emanzini ukuze yenze i-emulsion ezinzileyo, kwaye ukusabalalisa ubungakanani be-particle kufana ne-emulsion yasekuqaleni. I-powder yerabha ene-redispersibility embi, engenakuguqulwa ngokufanayo, kwaye inokuba ne-polymers engabonakaliyo.

2. Iimpawu zokwenza ifilimu ye-rubber powder: Iimpawu zokwenza ifilimu zisisiseko seempawu zokuguqula udaka ezifana nokunamathela. Iipropati zokwenza ifilimu ezingalunganga zibangelwa ngokubanzi ukongezwa kwezinto ezingaphiliyo okanye izinto ezingafanelekanga. Umgangatho olungileyo we-latex powder onokuthi uphinde uhlawulwe uneempawu ezilungileyo zokwenza ifilimu kwiqondo lobushushu begumbi, kwaye abo baneempawu zokubumba iifilim ezihlwempuzekileyo kwindawo yobushushu begumbi ubukhulu becala baneengxaki zomgangatho ngokwepolymer okanye umxholo wothuthu.

3. Ukunganyangeki kwamanzi kwefilimu: Umgubo we-latex owenziwe ngokutsha uneempawu ezilungileyo zokwenza ifilimu kwaye unokumelana nokuchasana kwamanzi. Umgubo weLatex onganyangekiyo emanzini ngokubanzi uqulathe iipholima ezininzi ezinyibilikayo emanzini.

3. Uhlalutyo lwempembelelo yesicelo

Imiselwa ngokomgangatho osebenzayo:

1. Amandla ebhondi eyomileyo kunye nokuqina kwebhondi enganyangekiyo emanzini: ibhondi ayilungile, kwaye kukho iingxaki ezisemgangathweni ngokwepolymer okanye umlotha.

2. Ukuguquguquka kunye nokuchasana kwempembelelo: Ukuguquguquka akulungile, kukho iingxaki ezisemgangathweni kwi-polymer, kwaye ukuguquguquka kuncipha ngexesha lokusetyenziswa, okunokuthi kuqulethe i-plasticizers.

3. I-Hydrophobic kunye ne-non-hydrophobic: I-surface i-hydrophobic kakhulu, enokunciphisa ukusebenza kunye namandla okudibanisa kodaka.

4. Ukuhamba kunye ne-rheology: I-rheology ayilungile, kwaye kukho iingxaki ezisemgangathweni kwiipolymers okanye izongezo.

5. Ukukhupha amagwebu kunye nokukhupha amagwebu: Ukuziphatha okungaqhelekanga kogwebu, iingxaki ezisemgangathweni ngeepholima, uthuthu okanye izongezo.

◆ Iindlela ezininzi ezilula zokuchonga umgubo we-latex odityanisiweyo:

1. Indlela yokubonakala: gubungela umlinganiselo omncinci we-latex powder ohlaziywayo ngokucokisekileyo kwaye ngokulinganayo phezu kwendawo ecocekileyo yeglasi kunye nentonga yeglasi, ubeke isitya seglasi kwiphepha elimhlophe, kwaye ujonge ngokubonakalayo ukubonakala kweengqungquthela, izinto zangaphandle kunye ne-coagulation.

2. Indlela yokuphelisa: Thatha umgubo omncinci welatex ophinda uhlakazwe kwaye uwubeke kumaxesha ama-5 amanzi, ugxobhoze kuqala kwaye ulinde imizuzu emi-5 ukuze ubone. Ngokomgaqo, into encinci enganyibilikiyo ewela kumaleko asezantsi, ingcono umgangatho we-latex powder ephindayo.

3. Indlela yothuthu: Thatha umlinganiselo othile womgubo welatex onokuphinda uhlakazwe, uwulinganise, uwubeke kwisitya sentsimbi, uwutshise ukuya kutsho malunga nama-600 degrees, uwutshise kubushushu obuphezulu malunga nemizuzu engama-30, uwupholise kwiqondo lobushushu begumbi, uze uwulinganise. kwakhona. Umgangatho olungileyo wobunzima obulula.

4. Indlela yokwenza ifilimu: Thatha umlinganiselo othile womgubo welatex odispersible, uwubeke kumaxesha ama-2 amanzi, ugxobhoze ngokulinganayo, uvumele ume imizuzu emi-2, uvuselele kwakhona, uqale ugalele isisombululo kwiglasi eflethi, emva koko iglasi Beka. kumthunzi ongena umoya. Emva kokumisa, qaphela ukuba umgangatho ocacileyo ophezulu ulungile.
