Funda Ngokukhiqizwa Kwebhodi Eliqhubekayo Le-Polyurethane Ku-athikili Eyodwa

Njengamanje, embonini yamaketanga abandayo, amabhodi okufakwa kwe-polyurethane angahlukaniswa abe yizinhlobo ezimbili ngokusekelwe endleleni yokukhiqiza: amabhodi okufakwa kwe-polyurethane aqhubekayo kanye namabhodi okufakwa ngesandla avamile.

Njengoba igama liphakamisa, amabhodi enziwe ngezandla akhiqizwa ngesandla.Lokhu kuhilela ukugoqa imiphetho yepuleti lensimbi elinamekwe ngombala ngomshini, bese ufaka ngesandla i-keel ezungezile, ukufaka iglue, ukugcwalisa okubalulekile, nokuyicindezela ukuze wenze umkhiqizo wokugcina. 

Amabhodi aqhubekayo, ngakolunye uhlangothi, enziwa ngokucindezela ngokuqhubekayo amaphaneli wesangweji sensimbi yombala.Emgqeni wokukhiqiza okhethekile, imiphetho yepuleti lensimbi evalwe ngombala kanye nezinto eziyinhloko ziyahlanganiswa futhi zisikwe kusayizi ngesikhathi esisodwa, okuholela emkhiqizweni oqediwe.

Amabhodi enziwe ngezandla angokwesiko, kuyilapho amabhodi aqhubekayo aye avela kancane kancane eminyakeni yamuva.

Okulandelayo, ake sibheke amabhodi okufakwa kwe-polyurethane akhiqizwa umugqa oqhubekayo.

1.Inqubo Yokukhiqiza

Inqubo yethu yokukhiqiza ihlanganisa imishini ecwebezelayo ye-polyurethane ephezulu kanye nomugqa wokukhiqiza webhodi oqhubekayo ozenzakalelayo.Lo mugqa wokukhiqiza uhlanganisa isixhumi esibonakalayo esisebenziseka kalula esenza kube lula ukusebenza nokuqapha.Izilawuli zekhompyutha ezithuthukisiwe zenza kube lula ukulungisa amapharamitha kuwo wonke ulayini, okuqinisekisa ukusebenza okuzinzile nokusheshayo.

Akukhona nje ukuthi umugqa wokukhiqiza uziqhayisa ngokusebenza okuhle kakhulu, kodwa futhi ubonisa ukunaka okwedlulele kwekhwalithi kuyo yonke imininingwane.Umklamo ucabangela ngokugcwele izidingo ezihlukahlukene zokukhiqiza kwangempela, uqinisekisa ukusebenza kahle okuphezulu ngenkathi kunciphisa kakhulu ubunzima bokusebenza.Ukwengeza, umugqa wokukhiqiza ufaka izinga eliphezulu lokuzenzakalela kanye nobuhlakani, ukunciphisa ukugxambukela kwabantu futhi kuthuthukise ukuvumelana nokuthembeka kwemikhiqizo.

Inqubo evamile yomugqa wokukhiqiza webhodi we-polyurethane eqhubekayo ihlanganisa izinyathelo ezilandelayo:

lUkuqaqa okuzenzakalelayo

lUkugqoka ifilimu nokusika

lUkubumba

lIfilimu lamination endleleni roller interface

lUkushisa kuqala ibhodi

lUkukhihliza amagwebu

lUkwelapha ngamabhande amabili

lI-band saw cutting

lIndlela ye-roller esheshayo

lUkupholisa

lUkupakisha okuzenzakalelayo

lUkupakishwa komkhiqizo wokugcina

2. Imininingwane Yenqubo Yokukhiqiza

Indawo yokwakha iqukethe izinto zokwakha amaroli angaphezulu naphansi kanye nendlela yokushintsha ngokushesha.Lokhu kusetha kuvumela ukukhiqizwa kwezimo zebhodi ezihlukahlukene ukuze kuhlangatshezwane nezidingo ezihlukahlukene zamakhasimende.

Indawo enegwebu ifakwe umshini wokugcwalisa ugwebu we-polyurethane ephezulu, umshini wokuthulula, kanye ne-laminator enamabhande amabili.Lokhu kuqinisekisa ukuthi amabhodi afakwe amagwebu afanayo, aminyene futhi aboshwe ngokuqinile.

Indawo yokusika i-band ihlanganisa isaha yokulandelela kanye nomshini wokugaya onqenqemeni, osetshenziselwa ukusika amabhodi ngokunembile ubukhulu obudingekayo.

Indawo yokupakisha neyokupakisha ihlanganisa amarola asheshayo, isistimu yokuziphendulela, ukupakisha, namasistimu okupakisha.Lezi zingxenye zisingatha imisebenzi efana nokuthutha, ukuphequlula, ukuhambisa, nokupakisha amabhodi.

Wonke lo mugqa wokukhiqiza uthuthukisa ukusebenza kahle ngokuqedela imisebenzi efana nebhodi lezokuthutha, ukuphenyisa, ukunyakaza, nokupakisha.Uhlelo lokupakisha luqinisekisa ukuthi imikhiqizo ivikelwe kahle ngesikhathi sokukhiqiza nokuthutha, igcina ukusebenza okuphezulu kanye nekhwalithi ezinzile.Ulayini wokukhiqiza usetshenziswe kabanzi futhi wanconywa kakhulu ngokusebenza kwawo.

3.Izinzuzo zamabhodi okugqumisa amalayini aqhubekayo

1) Ukulawulwa Kwekhwalithi

Abakhiqizi bamabhodi okushisa batshala imali emigqeni yokukhiqiza ezenzakalelayo futhi basebenzise amasistimu okukhipha amagwebu anengcindezi ephezulu.Ngokuvamile, kusetshenziswa i-pentane-based polyurethane foaming system, eqinisekisa ukugcwaliswa kwegwebu okufanayo ngenani lamaseli avaliwe ngokuqhubekayo ngaphezu kwama-90%.Lokhu kubangela ikhwalithi elawulekayo, ukuminyana okufanayo kuzo zonke izindawo zokulinganisa, kanye nokumelana nomlilo okuhle kakhulu kanye nokushisa okushisayo. 

2) Ubukhulu obuguquguqukayo

Uma kuqhathaniswa namabhodi enziwe ngezandla, ukukhiqizwa kwamabhodi aqhubekayo kuvumelana nezimo.Amabhodi enziwe ngezandla anqunyelwe indlela yawo yokukhiqiza futhi awakwazi ukukhiqizwa ngamasayizi amakhulu.Amabhodi aqhubekayo, nokho, angenziwa ngokwezifiso kunoma imuphi usayizi ngokwezidingo zamakhasimende, ngaphandle kokulinganiselwa kosayizi. 

3) Ukwenyuswa Kwekhono Lokukhiqiza

Umugqa wokukhiqiza oqhubekayo we-polyurethane u-automated ngokugcwele, nokwakhiwa kwebhodi elihlanganisiwe futhi asikho isidingo sokungenelela ngesandla.Lokhu kuvumela ukusebenza okuqhubekayo kwamahora angu-24, amandla okukhiqiza aqinile, imijikelezo emifushane yokukhiqiza, nezikhathi zokuthumela ngokushesha.

4) Ukusebenzisa kalula

Amabhodi e-polyurethane aqhubekayo asebenzisa isakhiwo solimi-ne-groove ekuxhumekeni okuxhumene.Ukuxhuma kuqiniswa ngama-rivets kokubili phezulu nangaphansi, okwenza ukuhlangana kube lula futhi kunciphise isikhathi esidingekayo sokwakhiwa kwesitoreji esibandayo.Ukuxhumana okuqinile phakathi kwamabhodi kuqinisekisa ukungena komoya okuphezulu kuma-seams, kunciphisa amathuba okuguqulwa ngokuhamba kwesikhathi.

5) Ukusebenza Okuphezulu

Ukusebenza okuphelele kwamabhodi aqhubekayo e-polyurethane asekelwe kwi-pentane kuzinzile, ngesilinganiso sokumelana nomlilo esifinyelela ku-B1.Banikeza ukufakwa kwe-thermal okuhle kakhulu futhi badlule izindinganiso zikazwelonke, bahlangabezane nezidingo zabasebenzisi abahlukahlukene besitoreji esibandayo.
