Ikhiqizwa kanjani i-polyethylene Foam?

Ungaqiniseki ukuthi i-penoam yenziwa kanjani? Ukukhetha uhlobo olungalungile kungalimaza ukusebenza futhi kwandise izindleko. Ake sihlukanise inqubo nezinto zokwakha ngendlela elula kuwe.

I-polyethylene Foam ikhiqizwa ikakhulukazi ngokushisa ama-polyethylene Plastic pellets ahlanganiswe ne-ejenti evuthayo. Ngaphansi kwezimo ezilawulwayo, ingxube inwebeka futhi yakha isakhiwo samaselula njengoba ipholisa, imvamisa ngenqubo yokukhishwa.

Ukwazi izisekelo kuyasiza, kepha kwenzeka kanjani ukuthi uPe Peam ehlangene negxathu? Iziphi izinto ezithile ezisetshenziswayo, nokuthi yiziphi izinhlobo ezitholakalayo? Ukuqonda le mininingwane kungakusiza wenze izinqumo ezinhle. Ake sihambe ngezinto zokwenziwa, inqubo yokukhiqiza, amazinga okuqina, nokuthi kuqhathaniswa kanjani namagwebu afanayo afana ne-EPE. Namathela nathi ngokubheka okucacile kokuthi i-Pe Foam yenziwa ngayo.

Yiziphi izinto zokwakha ezisetshenziselwa ukwenza i-polyethylene Foam (PE FOAM)?

Ukukhetha izinto ezifanele kungabonakala zinzima, kepha ukusebenzisa okungalungile kuholela ezinkingeni ze-foam ezingezinhle nezinkinga zokusebenza. Lapha, sizodiliza izithako ezibalulekile ezidingekayo ukukhiqiza i-Foam ethembekile.

Izinto ezingavuthiwe eziluhlaza ze-PE Foam yi-polyethylene (pe) resin, imvamisa ngefomu le-pellet. Izengezo ezibalulekile zifaka i-ejenti evuthayo ukwakha amaseli kaFoam, kanye nama-ejenti wokuxhumanisa oxhumanisayo, ama-colorants, noma ukuqina, kuya ngezakhiwo zokugcina ezifiselekayo.

Ake sibhekisise ukuthi yini engena kwi-Pe Foam esiyakha eTopsun. Konke kuqala ngopulasitiki wesisekelo:

● I-Polyethylene (PE) Resin : Lokhu kuyinto ebaluleke kakhulu, ngokuvamile kunikezwa njenge-pellets encane, eqinile. Singakwazi ukukhetha ezinhlotsheni ezahlukahlukene ze-PE, njenge-polyethylene ephansi (LDPE) ye-softer, i-foam eguquguqukayo, noma i-polyethylene ephezulu (HDPE) ye-spiffer, igwebu eliqinile. Ukukhetha kuncike ngokuphelele kwinhloso ehlosiwe ye-foam.

● Umenzeli ovuthayo : Lesi sithako esiyisihluthulelo sakha isakhiwo sikaFoam. Lapho ipulasitiki ifudunyezwa futhi icutshungulwa, i-ejenti evuthayo ikhipha igesi, yakha ama-bubble amancane noma amaseli ngaphakathi kokuqukethwe futhi ayikhulise ku-foam. Ama-ejenti aqhuma angaba ngamakhemikhali (aqhekeze ukukhipha igesi) noma ngokomzimba (njengokujova i-nitrogen noma i-hydrocarbons).

● Ama-ejenti axhumanisa anqamula (ngokuzithandela kodwa okujwayelekile) : Ngezinhlobo ezithile ze-PE FOAM, njenge-Xpe ne-IXPE, kufakwa amakhemikhali akhethekile. Lawa ma-ejenti akha izibopho eziqinile zamakhemikhali phakathi kwama-polyethylene molecule ngesikhathi sokucutshungulwa. Lokhu kuxhumanisa kuthuthukisa amandla egwebu, ukumelana nokushisa, kanye nemiphumela ngesakhiwo seseli esihle kakhulu.

● Ezinye izithasiselo : Ngokuya ngokusetshenziswa okuhlosiwe, singafaka ama-colorants ngama-aesthetics athile, abaqiniswa i-UV ngokuqina kwangaphandle, noma izithiyo zomlilo ukufeza imithetho yezokuphepha. 

Ungakhiqiza kanjani i-peoam?

Udidekile ukuthi senziwa kanjani i-peoam? Ukungaqondi inqubo kungathinta ukulawulwa kwekhwalithi nokukhethwa kwezinto ezibonakalayo. Ake siqhubeke ngezinyathelo ezijwayelekile ezihilelekile ekukhiqizeni i-FOAM.

I-FOAM ngokuyinhloko yenziwa ngenqubo yokukhishwa. I-PolyethLlene Resin kanye nezengezo zincibilika futhi zihlanganiswa emshinini owaziwa ngokuthi yi-extruder. I-ejenti evuthayo yakha ama-bubble kagesi, okwenza ukuthi ingxube yandise njengoba idlula ngokuvulwa okubunjiwe (ukufa). I-Foam isepholile futhi yakhiwa ngamashidi, ama-roll, noma amapulangwe.

Ake ngikuqondise kwinqubo ejwayelekile, kusuka kuma-pellets epulasitiki ukuqeda i-Foam sheet noma umqulu, njengoba sivame ukuphatha abahlinzeki bethu lapha eTopsun. Indlela ejwayelekile esiyisebenzisayo ukukhishwa.

● Ukuncibilika nokuxubanisa : Ama-pellets aqinile awokudla, kanye nanoma yiziphi izithasiselo ezidingekayo ezinjengezibalo noma ezikhuthele, zondliwa emgqonyeni ovuthayo obizwa ngokuthi yi-extruder. Ngaphakathi, isikulufa esijikelezayo sincibilika ipulasitiki futhi sihlanganisa kahle izithako zibe ngoketshezi olushisayo, obukhulu.

● Ukushayisana umjovo we-ejenti: I-ejenti evuthayo ifakwa ngaphansi kwengcindezi ephezulu epulasitiki ebilisiwe endaweni ebekiwe ku-extred, lapho ihlakazeka khona noma ihlakazeka ngokufana kuncibilika kuncibilike.

● Ukukhishwa kanye nokwanda : Ingxubevange ecindezelwe iphoqelelwa ukuvulwa okubunjiwe, owaziwa ngokuthi yi-die. Njengoba ipulasitiki elibunjiweyo liphuma kufa, ingcindezi yehla ngokushesha, okwenza ukuthi i-ejenti eshayelwe ichithekile ukwakha ama-bubble kagesi. Lokhu kunwetshwa okusheshayo kwakha isakhiwo se-foellar foam. Ukwakheka kokufa kuyacelwa ukuthi i-foam iphuma njengephepha eliyisicaba, iphrofayli eliyindilinga, noma esinye isimo.

● Ukupholisa nokuqina : Igwebu elisanda kukhiqizwa ngokushesha lipholile, ngokujwayelekile ngokuchayeka emoyeni noma emanzini. Le nqubo epholile yenza lukhuni ipulasitiki, ikhiya kuma-bubble futhi iqinise ukwakheka kwe-foam kokugcina kanye nokwakheka kwamaselula.

● Ukuxhumanisa okunqamula (nge-Xpe / IXPE) : Yilapho kwenziwa khona izinhlobo ezithile.

1.I-XPE (Chemical Cross-Ixhumene) : Kule nqubo, ama-ejenti wokuxhuma amakhemikhali angeniswa ngesikhathi sokuxuba. Ukushisa okuvela ku-extruder kusebenze la ma-ejenti, kwakha izibopho phakathi kwama-polyethylene (pe) molecule kungaba ngaphambi noma ngesikhathi sokunweba. Le ndlela isetshenziswa kabanzi emakethe yaseChina.

2.I-IXPE (i-Irradiated exhunyiwe): Ngale ndlela, ukuxhumeka kwesiphambano kwenzeka ngemuva kokuthi ishidi le-foam likhishwe futhi lipholile. Ishidi eliqinile livezwa ugongolo lwe-elektroni (i-irradiation), lapho imisebe yamandla aphezulu idonsa ngokuxhumanisa ama-molecular. Uma kuqhathaniswa ne-Xpe, i-ixpe imvamisa ibonisa indawo ebushelelezi, isakhiwo se-cell cell esilungile, futhi ithuthukise izakhiwo zomzimba - okwenza kube kuhle ngezicelo zokusebenza okuphezulu. Kodwa-ke, ubuchwepheshe obuthuthukisiwe kanye nemiphumela ephakeme iza ngezindleko eziphakeme.

Ingabe i-polyethylene Foam ithambile noma inzima?

Dinga ibhalansi ephelele yokuthambisa nokusekelwa? Akuwona wonke amagwebu we-Pe ekwenzeni okufanayo - ukukhetha ukuqina okungalungile kungawushiya umkhiqizo wakho ovikelwe noma uqinile ngokweqile. Ake sikuqondise ngobuningi obuhle nesakhiwo sohlelo lwakho lokusebenza oluthile.

I-polyethylene Foam imvamisa iwela phakathi kokufakwa kwe-cushioning ezithambile nezinto eziqinile - i-firmer kune-plush pu amagwebu kepha ivumelana nezimo kunamapulasitiki anzima. Ukuqina kwalo ngqo kungahluka kakhulu, kusuka kuvumelana nezimo ku-stuff, kuya ngobuningi bayo nohlobo oluthile.

Lapho amaklayenti athandana noSarah abuza ukuthi ngabe i-Pe Foam ithambile ngokwanele ngezendlalelo zenduduzo e-PPE, noma lapho uDavid edinga isiqinisekiso sokulimela kwawo ngokuvikelwa kwezimboni, ngichaza ukuthi 'Ubulukhuni ' ku-PE FOAM. Ikhona kwi-spectrum. Uma kuqhathaniswa ne-squishy polyurethane foam ku-sofa yakho, iningi le-pe peoam lizwa i-firmer ebonakalayo nokuqina ngokwengeziwe. Ibamba ukwakheka kwayo kube ngcono ngaphansi kwengcindezi.kodwa emndenini we-peoam, kunokuhlukahluka okubalulekile:

● Ubuningi bubalulekile : Lesi yinto enkulu kunazo zonke. I-Low-density PE FOAM (njengamabanga athile okupakisha noma i-epe) izizwa lilula futhi lithambile noma livumelana nezimo. I-High-Density Pe Foam isinda kakhulu, i-Spiffer, futhi inikeza ukumelana okwengeziwe ekucindezelweni. Sicacisa ubuningi ngokususelwa ku-cushioning noma ukwesekwa okudingekayo.

● Uhlobo lwe-Polymer : I-Foam eyenziwe nge-LDPE (ephansi-density polyethylene) i-resin ivame ukuba nezimo ngokwengeziwe kune-foam eyenziwe nge-HDPE (ephezulu-desity polyethylene) i-resin, ngisho nakumanye ama-densities afanayo.

● Ukuxhumanisa okuxhumeka : I-Foams exhumeke kakhulu (Xpe ne-IXPE) ngokuvamile zizwe i-firmer futhi iqine kakhulu kunama-foams axhumeke axhumeke axhumene nobunzima obufanayo. Ukuxhumeka okuphambanisa kuthuthukisa ubuqotho be-foom wesakhiwo, okwenza kwavela emuva kube ngcono ngemuva kokucindezelwa futhi uzizwe uqinile. I-ixpe, ngesakhiwo sayo seselula esisezingeni eliphakeme, imvamisa izizwa ishelelezi futhi inomfela omncane kuneXpe.

Ngakho-ke, ingabe uPe Foam angaba ''? Yebo, ukukhuluma, amabanga aphansi aphansi angashintshashintsha. Ingaba 'kanzima '? Nakanjani, ukuqina okuphezulu kanye nezinhlobo ezixhumene kakhulu zinikeza ukuqina okukhulu. Sisiza ekukhetheni ibanga eliqondile lokuvikelwa, ukusekelwa, futhi kwesinye isikhathi induduzo, ukuqinisekisa ukuthi i-foam ihlangabezana nezidingo ezithile zohlelo.
