Ngokuthuthuka okuqhubekayo kokuhlukahluka kanye nezidingo zokwenza ngokwezifiso zemakethe yezimpahla zabathengi yesimanje, isipontshi se-PU (isipontshi se-polyurethane), njengengxenye ebalulekile yokuvikela kanye nemikhiqizo yokwesekwa, sibhekene nokukhula kwesidingo semakethe okungakaze kubonwe ngaphambili. Kungakhathaliseki ukuthi imikhiqizo ye-elekthronikhi, impahla yasendlini noma ukupakishwa okuphezulu, isiponji se-PU (isipontshi se-polyurethane) singanikeza imiphumela yokuvikela eyingqayizivele. Lesi sihloko sizohlola izici zomkhiqizo we-sponge lining ekujuleni, futhi sigxile ekuhlaziyeni ukwenziwa ngokwezifiso kwesipontshi kanye namathemba okusetshenziswa kwesipontshi se-PU emakethe.
I. Survey Uhlolojikelele
Isiponji se-PU (i-polyurethane sponge) sithatha isikhundla esibalulekile emakethe ye-sponge linening ngokunwebeka kwaso okuphakeme kanye nokumelana nokugqoka. Isiponji se-PU asigcini nje ngokusebenza kahle kakhulu kwe-cushioning, kodwa futhi sinempilo ende yesevisi kanye nezindawo ezinhle zokulwa namagciwane kanye nesikhunta, okwenza kube ukukhetha kwezinto zokupakisha eziphezulu. I-PU sponge (i-polyurethane sponge) isiphenduke intandokazi embonini yokupakisha ngokusebenza kwayo okuhle kakhulu kwe-cushioning, ukumelana nokucindezela okuhle kanye nokuguquguquka ukuzivumelanisa ngokugcwele nezimo ezihlukahlukene. Akukwazi nje ukuvimbela ngempumelelo ukungqubuzana nokushayisana kwemikhiqizo ngesikhathi sokuthutha, kodwa futhi inikeza ukuvikelwa okwengeziwe ngokusebenzisa izinto ezithambile. Ulwelwesi lwesipontshi lubaluleke kakhulu lapho usebenza ngemikhiqizo kagesi nezinto ezintekenteke. Kungakhathaliseki ukuthi isetshenziselwa ukuvikela okokusebenza kwe-elekthronikhi okubalulekile, amathuluzi anembayo, noma ukupakishwa okuphezulu kwempahla yasendlini, isipontshi se-PU singanikeza ukuvikeleka okuhle kakhulu.
Ngokukhula kwamathrendi okusetshenziswa komuntu siqu, isidingo semakethe semigqa yesipontshi eyenziwe ngokwezifiso siyakhula. Ukwenza ngokwezifiso isipontshi kungenziwa ngokunembile ngokwesimo esithile kanye nezidingo zokusebenza zemikhiqizo ehlukene ngokusika, i-thermoforming nezinye izinqubo ukuze kuqinisekiswe ukuthi ucezu ngalunye lwesipontshi lungalingana kahle nesakhiwo esiyingqayizivele somkhiqizo. Siyabona ukuthi ukwenza ngokwezifiso isipontshi kusetshenziswa kakhulu kumawashi aphezulu, amabhokisi obucwebe kanye nokupakishwa kwemishini kagesi, futhi lesi sidingo semakethe sizokhula eminyakeni emihlanu ezayo.
2. Isimo semakethe
1. Usayizi wemakethe: Kusukela manje, usayizi wemakethe yegwebu le-PU emhlabeni jikelele ubonise ukuthambekela okukhuphukayo, futhi usayizi wemakethe yegwebu le-PU emhlabeni wonke uzodlula u-US$ 10 wezigidigidi ngo-2024. Eminyakeni embalwa ezayo, usayizi wemakethe kulindeleke ukuthi unwebe.
2. Inkambu yesicelo: Igwebu le-PU lisetshenziswa kabanzi kufenisha, izimoto, i-aerospace, ukwakhiwa kanye neminye imikhakha. Phakathi kwazo, imboni yezimoto inesidingo esikhulu kunazo zonke se-PU Foam futhi ithatha ingxenye enkulu yemakethe. Ngokuthuthuka okuqhubekayo kwempahla yasendlini nezinto zokwakha, isidingo segwebu le-PU sikhula kancane kancane
3. Ukuncintisana kwemakethe: Njengamanje, imakethe ye-PU Foam yomhlaba wonke inokuncintisana okukhulu, futhi abakhiqizi abakhulu bahlanganisa i-BASF, i-DowDuPont, i-Huntsman nezinye izinkampani ezaziwayo. Lezi zinkampani zenze kahle ocwaningweni nasekuthuthukisweni kwemikhiqizo, ezenzweni ezintsha zobuchwepheshe kanye nokwanda kwemakethe, futhi zinesabelo esikhulu semakethe.
4. Amathrendi ezimakethe: Imakethe ye-PU Foam yesikhathi esizayo izokhombisa izitayela ezilandelayo: Okokuqala, ukuvikela okuluhlaza kanye nemvelo. Ngokuthuthukiswa kokuqwashisa ngemvelo, isidingo sabathengi sezinto eziluhlaza nezingangeni emvelweni siyaqhubeka nokwanda. Abakhiqizi be-PU Foam kufanele bakhulise utshalomali lwabo ekuvikelweni kwemvelo futhi bakhuthaze ukukhiqizwa okuluhlaza. Okwesibili, ubuhlakani. Ngokuthandwa nokuthuthukiswa kokuzenzakalelayo kwezimboni, imikhiqizo ehlakaniphile ye-PU Foam izothandwa yimakethe. Okwesithathu, imikhiqizo eminingi ye-PU Foam yesikhathi esizayo izothuthuka ibheke ekusebenzeni okuningi ukuze ihlangabezane nezidingo zemikhakha ehlukene.
Kafushane, inani le-sponge lining emakethe yesimanje yokupakisha liyabonakala. Ngokuhlaziywa okujulile kokwenziwa ngokwezifiso kwesipontshi kanye nesipontshi se-PU, kungabonwa kusengaphambili ukuthi isidingo semakethe somugqa wesipontshi sizokhuphuka kakhulu eminyakeni emihlanu ezayo. Lo mkhuba awulethi nje kuphela amathuba emakethe amaningi embonini, kodwa futhi ubeka izidingo eziphakeme ekukhiqizeni isipontshi kanye nocwaningo nokuthuthukiswa. Ngenkathi zamukela leli thuba lokukhula, izinkampani zidinga ukuqhubeka nokusungula nokuthuthukisa ukusebenza komkhiqizo ukuze zihlangabezane nezidingo ezikhulayo nezihlukene zabathengi.
Ngokuzayo, ngokuphindaphinda okuqhubekayo kanye nokuqanjwa okusha kwemikhiqizo ehlukahlukene ye-sponge lining, lo mkhakha ngokuqinisekile uzoletha ithemba lentuthuko elihle kakhulu.
