Funda malunga nePolyurethane eqhubekayo yokuVeliswa kweBhodi kwiNqaku elinye

Okwangoku, kwishishini le-cold chain, iibhodi zokugquma i-polyurethane zinokwahlulwa zibe ziindidi ezimbini ezisekelwe kwindlela yokuvelisa: iibhodi ze-polyurethane eziqhubekayo kunye neebhodi ze-insulation zezandla eziqhelekileyo.

Njengoko igama libonisa, iibhodi ezenziwe ngezandla ziveliswa ngesandla.Oku kubandakanya ukusonga imiphetho yentsimbi egqunywe ngombala ngomatshini, emva koko ufakele i-keel ejikelezileyo, ugalele iglu, ugcwalise izinto ezingundoqo, kwaye uyicinezele ukwenza imveliso yokugqibela. 

Iibhodi eziqhubekayo, ngakolunye uhlangothi, zenziwe ngokucofa ngokuqhubekayo iipaneli zesandwich zentsimbi.Kumgca wemveliso okhethekileyo, imiphetho yeplate yentsimbi egqunywe ngombala kunye nezinto ezingundoqo zibotshelelwe kwaye zisikwe kubungakanani ngexesha elinye, okukhokelela kwimveliso egqityiweyo.

Iibhodi ezenziwe ngezandla ziqhelekileyo, ngelixa iibhodi eziqhubekayo ziye zavela ngokuthe ngcembe kwiminyaka yamuva.

Emva koko, makhe sijonge iibhodi zokugquma i-polyurethane eziveliswa ngumgca oqhubekayo.

1.INkqubo yeMveliso

Inkqubo yethu yokuvelisa ibandakanya izixhobo ezikumgangatho ophezulu we-polyurethane we-foaming kunye nomgca wokuvelisa ibhodi eqhubekayo.Lo mgca wemveliso ubonisa i-interface-friendly interface eyenza lula ukusebenza kunye nokubeka iliso.Ulawulo oluphezulu lwekhompyuter lwenza kube lula ukulungisa iiparamitha kuwo wonke umgca, ukuqinisekisa ukusebenza okuzinzile kunye nokukhawuleza.

Akukuphela nje ukuba umgca wemveliso uqhayisa ukusebenza kakuhle, kodwa ubonisa ingqwalasela egqithiseleyo kumgangatho kuzo zonke iinkcukacha.Uyilo luqwalasela ngokupheleleyo iimfuno ezahlukeneyo zemveliso yangempela, ukuqinisekisa ukusebenza kakuhle ngelixa kunciphisa kakhulu ubunzima bokusebenza.Ukongezelela, umgca wemveliso ubonisa umgangatho ophezulu wokuzenzekelayo kunye nobukrelekrele, ukunciphisa ukuphazamiseka kwabantu kunye nokuphucula ukuhambelana nokuthembeka kweemveliso.

Inkqubo eqhelekileyo yomgca webhodi ye-polyurethane eqhubekayo iquka la manyathelo alandelayo:

lUkuzikhulula ngokuzenzekela

lUkufakwa kwefilimu kunye nokusika

lUkubumba

lFilm lamination kwindlela roller interface

lUkufudumeza ibhodi

lUgwebu

lUkunyanga ibhanti kabini

lIbhendi isarha yokusika

lIndlela yerola ekhawulezayo

lUkupholisa

lUkupakisha okuzenzekelayo

lUkupakishwa kwemveliso yokugqibela

2. Iinkcukacha zeNkqubo yeMveliso

Indawo yokwenza iqulathe isixhobo sokwenza umqulu ophezulu nasezantsi kunye nesixhobo sokutshintsha ngokukhawuleza.Olu cwangciso luvumela ukuveliswa kweemilo zebhodi ezahlukeneyo ukuhlangabezana neemfuno ezahlukeneyo zabathengi.

Indawo enegwebu ixhotyiswe ngomatshini wokupholisa amagwebu wepolyurethane, umatshini wokugalela, kunye nelaminatha enamabhanti amabini.Ezi bhodi ziqinisekisa ukuba iibhodi zinegwebu ngokufanayo, zipakishwe ngokuxineneyo, kwaye ziboshwe ngokuqinileyo.

Indawo yokusika ibhendi ibandakanya i-saw tracking kunye nomatshini wokugaya, ezisetyenziselwa ukusika okuchanekileyo kweebhodi ukuya kwimilinganiselo efunekayo.

Indawo yokupakisha kunye nokupakishwa iqulethwe ziirola zokuthutha ezikhawulezayo, isistim sokuziphethula ngokuzenzekelayo, ukupakisha, kunye neenkqubo zokupakisha.Ezi zixhobo zijongana nemisebenzi efana nokuthutha, ukuzulazula, ukuhambisa, kunye nokupakisha iibhodi.

Lo mgca wemveliso uphela uphucula ukusebenza kakuhle ngokugqiba imisebenzi efana nokuthuthwa kwebhodi, ukuphaphatheka, ukuhamba, kunye nokupakishwa.Inkqubo yokupakisha iqinisekisa ukuba iimveliso zikhuselwe kakuhle ngexesha lokuvelisa kunye nokuthutha, ukugcina ukusebenza okuphezulu kunye nomgangatho ozinzile.Umgca wemveliso usetyenziswe ngokubanzi kwaye unconywa kakhulu ngokusebenza kwayo.

3.Izinto eziluncedo kwiiBhodi ze-Continuous Line Insulation

1）Ulawulo lomgangatho

Abavelisi beebhodi ze-insulation batyala imali kwimigca yemveliso ezenzekelayo kwaye basebenzise iinkqubo zokukhupha amagwebu ngoxinzelelo oluphezulu.Ngokuqhelekileyo, inkqubo ye-pentane-based polyurethane foaming isetyenzisiweyo, eqinisekisa ukuba i-foaming ifanayo kunye nesantya seeseli ezivaliweyo ngokuqhubekayo ngaphezu kwe-90%.Oku kubangela umgangatho olawulekayo, ingxinano efanayo kuzo zonke iindawo zokulinganisa, kunye nokumelana nomlilo okugqwesileyo kunye nokufakwa kwe-thermal. 

2) Imilinganiselo eguquguqukayo

Xa kuthelekiswa neebhodi ezenziwe ngezandla, ukuveliswa kweebhodi eziqhubekayo kuguquguquka ngakumbi.Iibhodi ezenziwe ngezandla zilinganiselwe ngendlela yazo yokuvelisa kwaye azikwazi ukuveliswa ngobukhulu obukhulu.Iibhodi eziqhubekayo, nangona kunjalo, ziyakwazi ukulungelelaniswa nakweyiphi na isayizi ngokweemfuno zabathengi, kungekho mida yobukhulu. 

3)Ukwandiswa koMveliso

Umgca wokuvelisa oqhubekayo we-polyurethane uzenzekelayo ngokupheleleyo, kunye nokwenza ibhodi edibeneyo kwaye akukho mfuneko yokungenelela ngesandla.Oku kuvumela ukusebenza ngokuqhubekayo kweeyure ezingama-24, amandla okuvelisa amandla, imijikelezo emfutshane yokuvelisa, kunye namaxesha okuthumela ngokukhawuleza.

4) Ukusebenziseka lula

Iibhodi ze-polyurethane eziqhubekayo zisebenzisa isakhiwo solwimi kunye ne-groove ukudibanisa ukudibanisa.Ukudibanisa kuqiniswe ngee-rivets kuzo zombini iziphelo eziphezulu kunye nezantsi, okwenza indibano ibe lula kunye nokunciphisa ixesha elifunekayo lokwakhiwa kokugcinwa okubandayo.Uxhulumaniso oluqinileyo phakathi kweebhodi luqinisekisa umoya ophezulu kwii-seams, ukunciphisa amathuba okuba nokuguqulwa kwexesha.

5）Ukusebenza okuPhezulu

Ukusebenza ngokubanzi kweebhodi eziqhubekayo ze-pentane-based polyurethane zizinzile, kunye nokumelana nomlilo ukuya kwi-B1.Banikezela nge-insulation egqwesileyo ye-thermal kunye nokugqithisa imigangatho yelizwe, ukuhlangabezana neemfuno zabasebenzisi abahlukeneyo bokugcina okubandayo.
