Ukulinganisa kunye nokulawula i-viscosity ezenzekelayo kubalulekile ukulawula ukwakheka kwe-coating kunye ne-viscosity yesicelo kwinkqubo ye-coating ye-wire. Ukuqinisekisa ukuba i-coating esemgangathweni ophezulu, efanayo, utshintsho kwi-viscosity kuyo yonke inkqubo lujongwa ngexesha langempela, lwenza imilinganiselo ukusuka kwisiseko kunokuba ilinganise nje amaxabiso apheleleyo.
Yintoni iCable Coating?
Ukufakwa kwentambo yinkqubo yokufaka umaleko okhuselayo okanye okhuselayo kwiintambo kunye neentambo ukuphucula ukuqina kwazo, ukusebenza kombane, kunye nokuxhathisa izinto ezingqongileyo. Oku kubandakanya ukufakwa kwentambo ye-enamel, apho umaleko omncinci wezinto zokukhusela, njenge-enamel esekwe kwi-polymer, ufakwa kwiintambo eziqhubayo ezifana nobhedu okanye i-aluminium ukuthintela imijikelezo emfutshane kunye nokukhusela ukufuma, ukukrala, kunye neekhemikhali. Umgangatho we-viscosity yokudibanisa ubalulekile ekufezekiseni ukufakwa kwe-coating efanayo, ukuqinisekisa ukugcinwa kwe-insulation rhoqo kunye nokuthembeka kwemveliso ngokubanzi kwizicelo ezisusela kwiimoto zombane ukuya kunxibelelwano.
Injongo yeNkqubo yokuGcoba
Inkqubo yokugquma intambo isebenza imisebenzi emininzi ebalulekileyo, ikakhulu ibonelela ngokhuseleko lombane kunye nokukhuselwa koomatshini kwiintambo kunye neentambo. Ikhusela iipropati ezifanelekileyo zentambo eyenziweyo kwiingozi zokusingqongileyo ezifana nokufuma, ubushushu, iikhemikhali kunye nokukrala ngelixa iphucula ixesha elide, kwaye iqinisekisa ukusebenza ngokukhuselekileyo kumashishini ahlukeneyo.
Oku kuquka ukukhusela ii-windings ekufunxeni umswakama kunye nemiphumo etshabalalisayo efana neoyile, ii-asidi, iikhemikhali, ubushushu, kunye nokukhula kwesikhunta, ngelixa ikwabopha iingcingo kunye ne-insulation zibe yinto eqinileyo, edibeneyo ukumelana nomothuko, ukungcangcazela, kunye noxinzelelo loomatshini. Ngaphezu koko, iphucula iipropati zombane ze-insulators, igcina ukusebenza kwimijikelo yobushushu nokubanda. Le nkqubo ithintela ii-short circuits, umonakalo woomatshini, kunye nokuwohloka kokusingqongileyo ngelixa iququzelela ukuchongwa ngemibala okanye iimpawu. Ngokubanzi, iphucula ukuqina, ukuguquguquka, kunye nokumelana nokukrala, ubushushu obugqithisileyo, kunye neekhemikhali zokusetyenziswa kwiimoto, ii-transformers, kunye neentambo ze-voltage ephezulu.
Isebenza njani inkqubo yokubopha iintambo?
Inkqubo yokugquma intambo ibandakanya amanqanaba aliqela okusebenzisa umaleko olinganayo wokukhusela, apho i-viscosity yokugquma idlala indima ebalulekileyo ekulawuleni ukuhamba kunye nokunamathela. Ngokwesiqhelo, ucingo olungenanto luyacocwa, lugqunywe nge-enamel okanye i-polymer, lunyangwe, luvavanywe. Inkqubo iqala ngokulungiswa kunye nokucoca, apho iingcingo zicocwa ukuze kususwe izinto ezingcolisayo, ukuqinisekisa ukunamathela okufanelekileyo.
Okulandelayo kuza ukusetyenziswa kwezinto, apho ucingo ludlula kwi-enamel bath okanye kwi-extrusion die apho izinto ezinyibilikisiweyo zinamathela khona, kunye nokuhamba kokujonga umlinganiselo we-viscosity ngaphakathi ukuze kugqunywe ubukhulu obufanayo. Oku kulandelwa kukupholisa, apho ucingo olugqunywe lufudunyezwa kwi-oven ukuze lukhuphe izinyibilikisi kwaye luqinise umaleko, luphindaphindwa rhoqo kwiindlela ezininzi ukuze kugqunywe ubushushu obukhulu. Emva koko, kuphola kwaye kujikelezwe, okuvumela ucingo ukuba luphole ukuze luzinzise ugqunywe ngaphambi kokuba lufakwe kwi-reels. Okokugqibela, ulawulo lomgangatho lwenziwa, kunye nee-viscometers ezingaphakathi zilungisa iiparameter ngexesha langempela ukugcina ugqunywe ngocingo lwe-enamel oluhambelanayo.
Zeziphi izinto ezisetyenziswa kwi-Cable Coating?
Kukhethwa iintlobo ngeentlobo zezinto zokwambathisa intambo ngokusekelwe kwiimfuno zokusetyenziswa, ezinje ngokugquma umbane, ukuguquguquka, kunye nokumelana nokusingqongileyo. Izinto eziqhelekileyo ziquka iipolymers kunye nee-enamel, ezinomxholo wezinto eziqinileyo ukusuka kwi-8% ukuya kwi-60% kunye ne-viscosity ephakathi kwe-30 kunye ne-60,000 mPas.
Iinketho eziphambili ziquka i-polyethylene (PE), enika amandla aphezulu e-dielectric kunye nokufuma kunye nokumelana neekhemikhali, kubandakanya iintlobo ezifana ne-LDPE yokuguquguquka kunye ne-HDPE yokuqina.
I-Polyvinyl chloride (PVC) ixabisa kancinci, ayitshisi ilangabi, kwaye iguquguquka, nto leyo eyenza ukuba ifaneleke kwiintambo ezisetyenziswa ngokubanzi. I-Cross-linked polyethylene (XLPE) iyakwazi ukufudumala kakuhle, ukurhawuzelelwa, kunye nokumelana neekhemikhali kwizicelo ze-high-voltage.
I-Polyurethane (PUR) inika ukumelana nokurhawuzelelwa kwiindawo ezinobungozi kunye nokunyibilikiswa kakuhle. I-Polyesterimide (PEI) kunye ne-THEIC-modified polyester (TPE) zii-enamel ezingatshisi ubushushu ezisetyenziswa rhoqo kwii-basecoats zeentambo zemagnethi.
I-Polyamide-imide (PAI) inika uzinzo oluphezulu lobushushu kwaye isetyenziswa njengee-topcoats zokuphucula oomatshini kunye neekhemikhali. Irabha ye-silicone iyakwazi ukumelana nobushushu kwaye izinzile kwiintambo zobushushu obuphezulu. Ezinye ii-enamel ezifana ne-polyvinylformal (PVF) kunye neentlobo ze-self-bonding, ezifana ne-epoxy-based, zihlangabezana neemfuno ezithile ze-bonding.
Amanqaku okulinganisa kwiNkqubo yokuGcoba ngeNtambo
Iindawo zokulinganisa zibalulekile ekujongeni ubungqingqwa bokugquma ukuqinisekisa ukugquma kobukhulu obufanayo. Ezi ziquka itanki yokuxuba ye-enamel okanye ibhafu, apho kuhlanganiswa khona izinto ezikrwada kunyeii-viscometer ezikwi-inlinefumanisa i-viscosity yokuqala. Umgca wokubonelela kwi-applicator uza emva koko, uvumela uhlengahlengiso lokutya ukuhambelana ngaphambi kokuba idaye okanye ibhafu. Amanqanaba emva kokufaka alandela, ebonelela ngokuqinisekiswa komgangatho wobukhulu kunye nokunamathela emva kokunyibilika. Kuyo yonke inkqubo, umlinganiselo we-viscosity oqhubekayo ubamba utshintsho ngexesha langempela ngenxa yobushushu okanye ukucheba.
Iingxaki Zangoku Kulawulo Lokuxinana
Ulawulo lokuxinana kwi-cable coating lujongene nemingeni emininzi, nto leyo edla ngokukhokelela ekungahambelani kwe-enamel wire coating. Ukuxhomekeka kuvavanyo olungaxhunyiwe kwi-intanethi yingxaki enkulu, njengoko iisampulu zelebhu zibangela ukulibaziseka kunye nokungachaneki kuba i-viscosity iyahluka ngobushushu kwaye i-smear offline.
Izinto ezikwimeko-bume, ezifana nokuphuma kwe-solvent evaporation, ukufuma, kunye nokutshintsha kobushushu, zitshintsha i-viscosity yokugquma ngendlela engalindelekanga. Indlela yokuziphatha ye-enamel engeyiyo eye-Newtonian yenza izinto zibe nzima ngakumbi, njengoko zitshintsha i-viscosity phantsi kwe-shear, zenza imilinganiselo ngezixhobo zemveli ezifana neekomityi ze-efflux ezimdaka kwaye ezingaphindiyo.
Ukunqongophala kwezixhobo nako kudlala indima, apho ii-viscometers ze-paddle zinengxaki yeempazamo zokufuma kunye neendlela ezenziwe ngesandla ezingakwaziyo ukubamba utshintsho olutshintshayo, nto leyo eyandisa ixesha lokungasebenzi kunye neemfuno zokugcinwa.
Iziphumo Ezimbi Ezibangelwa Kukungangqinelani Kwezinto
Ukungangqinelani kombala kubangela iziphene ezichaphazela ukusebenza kwentambo kwaye zonyuse iindleko. Oku kukhokelela ekungalinganini kobushushu, okubangela imingxunya yepin, amadyungudyungu, okanye ubukhulu obugqithisileyo obukhokelela kwiishothi zombane kunye nokungasebenzi kakuhle.
Ukwehla komgangatho nako kuyenzeka, kunye neengubo ezinamathelayo okanye ezigobileyo ezivela kwi-viscosity ephezulu okanye ephantsi ezinciphisa ukumelana nokungaguquguquki, ukuguquguquka, kunye neempawu zoomatshini.
Ukwanda kwenkunkuma yenye imiphumo, kuquka amazinga aphezulu enkunkuma elahliweyo, ukusetyenziswa kwesinyibilikisi, kunye nokulungiswa ngokutsha okuchaphazela inzuzo kunye nokuthobela imiqathango yokusingqongileyo.
Iingozi zokusebenza nazo ziyanda, nto leyo enokubangela ukuba imveliso ibuyiselwe, ukwaphulwa kwemithetho, kunye nokulahlekelwa kukwamkelwa kwemarike ngenxa yokumelana nokufiphala kakuhle kunye nokoma.
Iimfuneko zokubeka iliso kwi-Viscosity ngexesha langempela
Ukubeka iliso ngexesha langempela ngeii-viscometer ezikwi-inlineKubalulekile ukujongana nale micimbi ngokubonelela ngedatha eqhubekayo, okuvumela uhlengahlengiso olukhawulezileyo kwizinyibilikisi kunye nobushushu ukuze kubekho ukuxinana okuzinzileyo kokufaka. Inciphisa umahluko ngokuphelisa iimpazamo zesampulu kunye nokuqinisekisa ukugquma kobukhulu obufanayo ukusuka kwimilinganiselo yokuqala. Ukongeza, iphucula ukusebenza kakuhle ngolawulo oluzenzekelayo olunciphisa ukwaliwa, ixesha lokungasebenzi, kunye nemingcipheko yokuthobela imithetho kwimveliso ekhawulezayo.
Iingenelo zeLonnmeter Coating Viscometer Inline
