Bahlelwa njani oomatshini bokuphawula ezindleleni?
Ixesha:10-27-2020
Umatshini wokumakisha wendlela yeqela eliphindwe kabini: Ukumakishwa kwamacandelo amabini kukumakisha okuphezulu okuphuhliswe kwiminyaka yamuva.Ihluke ngokumakishwa kwe-hot-melt kunye nokumakishwa kweqondo lokushisa eliqhelekileyo ngenxa yokuhla kweqondo lokushisa okanye i-solvent (esekelwe emanzini) i-volatilization kunye nezinye iindlela zokomisa ngokwasemzimbeni ukwenza ifilimu yokugqoka.Umgca wokumakisha wamacandelo amabini luhlobo olutsha lomgca wokumakisha owenziwe yikhemikhali yangaphakathi ye-crosslinking ukwenza ifilimu yokugqoka.Umatshini wokumakisha wepavement enamacandelo amabini asetyenziselwa ukwakhiwa kwemigca yokumakisha yamacandelo amabini ahlulwe abe yi-spin coating structure, uhlobo lomgca osicaba kunye noxinzelelo oluphezulu lokutshiza olungenamoya ngokohlobo lwepeyinti esetyenzisiweyo kunye nenkangeleko yohlobo lomgca osetyenzisiweyo. .Iintlobo ezintathu zeumatshini wokumakisha wendlela onyibilikayo oshushu: Iphuhliswa ngokuthe ngcembe kwaye iphuculwe kunye nokuphuhliswa kweengubo ezishushu ezinyibilikayo, kwaye ngumatshini onomgangatho ophezulu wokuzenzekelayo.Ulwakhiwo lufuna iseti yezixhobo ukugqiba imisebenzi yokwakha ukusuka kwinyibilika ukuya kumakishwa.Olu luhlu lwezixhobo ngokubanzi lubandakanya iketile enyibilikayo eshushu, umatshini wokuphawula indlela (kubandakanya umatshini wokumakisha wecala lezebra), umatshini wokumakisha wangaphambi kwendlela, kunye nomatshini wokugquma ngaphantsi.
Ngokuqinisekileyo, abasebenzisi banokuthenga ulungelelwaniso lwezixhobo zeemodeli ezahlukeneyo, amabakala ahlukeneyo kunye nemisebenzi eyahlukeneyo ngokwamandla abo ezoqoqosho, ubungakanani bobunjineli kunye nenqanaba lobungcali.
Umatshini wokumakisha we-hot-melt kwi-configuration ungahlulwa ube ziintlobo ezintathu ze-hot-melt scraping type, i-hot-melt extrusion type kunye ne-hot-melt spraying ngokuhambelana neendlela zokumakisha ezahlukeneyo.Umatshini wokumakisha wendlela yobushushu obuqhelekileyo: uphawu oluqhelekileyo lobushushu luyimbali Enye yemigca yokumakisha yesiqhelo endala, olu hlobo lomgca wokumakisha ludla ngokugqityezelwa ngumatshini wokumakisha wendlela yobushushu begumbi.Umatshini wokumakisha wendlela yobushushu begumbi unokwahlulwa ube ziindidi ezimbini: uhlobo oluphezulu loxinzelelo olungenamoya kunye noxinzelelo oluphantsi loncedo lomoya ngokwendlela yokumakisha;ngokweentlobo ezahlukeneyo zokugquma okusebenzayo, yahlulwe ngohlobo oluqhelekileyo lobushushu, ubushushu obuqhelekileyo obusekelwe kumanzi kunye nohlobo lwe-solvent eshushu Iintlobo ezintathu (umatshini wokumakisha wendlela yobushushu obuqhelekileyo ubandakanya uhlobo lwamacandelo amabini, ngakumbi ukutshiza ngamacandelo amabini. uhlobo, luhlobo olubanzi lomatshini wokumakisha wendlela onomsebenzi wokugquma ubushushu obuqhelekileyo kunyeukutshiza ipeyinti enamacandelo amabini ).
