AKA-izinto - esetyenziswa kunye ntoni?

Mhlawumbi akukho namhlanje mntu akanako iniqubule ibinzana njengoko AKA-izinto eziphathekayo. Ntoni na, ke, ukwazi oko akubantwini bonke. yayisebenzisa Uphi na? Yintoni na? Indlela ukwahlula lyu thermoplastic ngenaliti? Nangona ukufana belanga, neendlela zokusebenza kunye neempawu umsebenzisi-ezahlukeneyo zabo ngokupheleleyo.

AKA-material - ntoni na?

Ke ngakumbi. AKA-material - ntoni na? Oko yayingako imiqondiso ezendeleyo kulo? Enyanisweni, kulula ukwahlula. Le nkcazelo wokuqala uhlobo encinane ntsalela, evumela ukusetyenziswa amanqaku ezenziwe kulo, njengoko amatywina. Okwesibini, AKA zingaphinda zisebenziseke kwakhona, nto leyo igcina phezu feedstock. Okwesithathu, xa lingekho eziphathekayo kuvala ngokupheleleyo. Okwesine, Lubonakala ngobomi inkonzo ende. Ngaphezu koko, izinto iyamelana lingonakali kunye haydrolisis amanyathelo ezincinane.

Enyanisweni, ezi umgangatho semvelo kunye polyurethanes afunyenwe indlela elula. Noko ke, kuphela AKA ekwaziyo zenziwa kwizixhobo eyenzelwe nokuveliswa iiplastiki zesiqhelo - oomatshini, izixhobo kunye imigca, ebizwa inaliti oomatshini sukube.

Xa kwaqala?

Kwaye ngoku isuntswana lembali. Xa kwabonakala AKA-eziphathekayo? Ziziphi ezi zizathu abukeke? Yonke le nto yaqala, ababhali-mbali bathi, njengokuba ekuqaleni 1865. Inkampani benza ezivelisa iibhola snooker, kwenziwa isaziso engaqhelekanga. Lowo ufumana izinto othatha ngeempondo zeendlovu, ngamawaka alishumi US iidola ziye thembisa. Ngowe-1869, Dzhon Hayat wagqiba ukusebenzisa nitrocellulose. Wakwazi ukufumana Obusemagqabini ubunjani kunye neepropati, emva koko wagqiba ukuseka inkampani yakhe. Ukususela ngoko waqalisa uphuhliso olukhawulezayo oomatshini udini inaliti kunye neemathiriyeli, ukuba zenziwa kanjani. Ukuza kuthi ga ngoku, icandelo liye lafikelela obude engakholelekiyo.

imveliso AKA

Yintoni inkqubo yokuvelisa? AKA-material - yintoni na kwimveliso? Makhe siqale izinto ekrwada. Kuba imveliso AKA efunekayo granules wafumana ngaphambili ngayo amacandelo lyu. Kakade ke, ekuqaleni bakuzuze kwiipropati ukuvumela eziphathekayo ukuze nokulungelelanisa. Inaliti yokubumba Umatshini hopper bahlaselwa ezi granules efanayo. Ngaphezu bondliwa yi jija kwindawo ukufudumeza. Emva koko, ubunzima zeplastiki zokuthenga lesitofu sokubumbela enoxinzelelo (ekwenziweni kwezinto ezinzima) okanye extruded, ngamanye extruded ngokusebenzisa amanzi esatsiba - uvula oluthile loqwalaselo (lokuvelisa amalungu ezilula, ezifana iintonga, imicu, sheets).

buhle

Ngokufutshane, ukuhlanganiswa iimpawu lwemichiza AKA kunye iindlela yokujongwa ivumela ukufumana izinto kunye emzimbeni iparameters yinzwakazi. Enye engundoqo, umzekelo, ukumelana eliphezulu ubushushu. Kuba uninzi iimveliso ezenziwe AKA, lobushushu Ukuthamba yokuqala degrees 120-140 Celsius. Kulo mzekelo, izinto iphela ngokupheleleyo kwakhona zonke iparameters yayo. Nangona polyurethanes eziqhelekileyo emva lobushushu ayide ikwazi wachacha.

Sele ekhankanywe nethuba yokurisayikilisha umbandela. iinxalenye yalo otyunyuziweyo, wathumela umva.

inzuzo olunzulu luvukelo eliphezulu ukunxiba. Ngoko ke, lo imveliso unako ukukhonza nje ukhuselo obalaseleyo. izinto Resistant nayo baboniswa UV. Ngokubanzi, zonke ezi iingenelo kwenza kube lula ukufumana izinto zomgangatho ophezulu, nto leyo baneempawu emangalisayo. Owenziwe le eziphathekayo, umzekelo, ihlanganisa for Samsung, Nokia kunye nezinye phones. Ezi mveliso zibe ithandwa enkulu namhlanje. Noko ke, ngaba ukhetha ntoni imveliso, qiniseka ukuba ahlale onwabile.
