Ulwazi lweshishini le-FOAM |Ukuthelekiswa kweempawu ezintathu zogwebu ze-polystyrene, i-polyurethane kunye ne-polyolefin

iplastiki yogwebu

Iplastiki enogwebu luhlobo lweplastiki efunyenwe ngokwenza ngokwasemzimbeni okanye ngokwekhemikhali ulwakhiwo lwemicrocellular ngaphakathi kweplastiki.Olu hlobo lweplastiki lunoncedo lobunzima bokukhanya, ukugquma ubushushu, ukugquma, ukugquma, ukunqanda ukubola kunye nexabiso eliphantsi.Phantse zonke iiplastiki ze-thermosetting kunye ne-thermoplastic zingenziwa kwiiplastiki ezinogwebu.Iiplastiki ezinogwebu eziqhelekileyo ziyi-polystyrene, i-polyurethane, kunye ne-polyolefin.

Ukuthelekiswa kweeplastiki ezinkulu ezintathu ezinogwebu

Intshayelelo yePolypropylene eFoamed

Ipolypropylene enogwebu yiplastiki enogwebu elungiselelwe ukusuka kwipolypropylene njengesiseko sentlaka.Xa kuthelekiswa neeplastiki ezinogwebu ezisetyenziswa ngokuqhelekileyo, i-polypropylene enegwebu ineengenelo ezininzi.

I-polypropylene enegwebu izinto ekrwada

Ekubeni amandla asezantsi okunyibilika kwepolypropylene eqhelekileyo ayinakuqinisekisa ukuxinzezeleka koxinzelelo kwiindonga zeseli xa amaqamza ekhula, i-polypropylene yokwenza ugwebu idinga ukusebenzisa i-polypropylene ephezulu yokunyibilika (HMSPP).

Iindlela zokuphucula amandla okunyibilika kwepolypropylene ziquka ukuxubana komzimba kunye nokuguqulwa kweekhemikhali.

Okwangoku, abavelisi bezinto eziphezulu ze-polypropylene ezinyibilikayo zibandakanya i-Basell, i-Borealis, i-Dow Chemical, i-Samsung, i-Exxon Mobil, njl.Amaziko amaninzi ophando lwasekhaya enze uphando oluninzi kwitekhnoloji yogwebu, kwaye abanye abavelisi baye baqaphela imveliso yemizi-mveliso, efana neZhenhai Refinery, Yanshan Petrochemical Resin Research Institute, Wuhan Futiya, kodwa kusekho umsantsa omkhulu phakathi komgangatho wemveliso kunye namazwe angaphandle. ..

Inkqubo yokuvelisa i-polypropylene enegwebu

Kukho iinkqubo ezintathu eziphambili zamalungiselelo: amandla aphezulu okunyibilika kwepolypropylene ukugwebu, ukuwela ugwebu lwepolypropylene, kunye nenkqubo yokudibanisa ugwebu.

Isitshixo sokulungiselela i-polypropylene enegwebu

Iimveliso zepolypropylene ezinegwebu zinokusebenza kakuhle kunye nethemba lokusetyenziswa, kodwa uphuhliso lobugcisa lunzima.Itekhnoloji ephambili yenkqubo yogwebu lwepolypropylene kukulawula ukuzinza kogwebu kunye nomlinganiselo ogwebu amagwebu wepolypropylene ngokulungelelanisa ubushushu benkqubo.

 
Iinkalo zokusetyenziswa kwepolypropylene enegwebu

1. Ukupakishwa kokutya

Ipolypropylene enogwebu inokonakala okulungileyo kunye nokuxhathisa okulungileyo kwe-oyile, nto leyo eyenza ukuba ibe neenzuzo ezicacileyo ngaphezu kokutya okwandisiweyo kwepolystyrene kwimarike yokupakisha elahlayo.

2. Ukufakwa kwe-thermal

Izinto zepolypropylene ezinegwebu luhlobo olutsha lwezinto zokufakelwa kwe-thermal ezinokumelana nobushushu obunamandla.Iqhele ukumelana nobushushu obuphakathi kwe-40 ukuya kwi-110 °C, kwaye inokumelana nobushushu obuphezulu obuyi-130 °C ngexeshana elifutshane.

3. Ushishino lweemoto

Kwiminyaka yakutshanje, ukusetyenziswa kwe-polypropylene ene-foam kumashishini eemoto iye yanda, enokunciphisa kakhulu ubunzima bemoto kunye nokugcina ukusetyenziswa kwepetroli.

4. Indawo yokwakha

Izinto zokukhuselwa kwamanzi, izinto zokugubungela umgangatho, izinto zokugquma eludongeni lwangaphandle

5. Ukupakishwa kwe-Electronic

6. Ukupakishwa kwe-buffer

7. Iimpahla zeMidlalo

8. Izinto zokudlala

Abavelisi abaphambili bepolypropylene enegwebu

Iimveliso zepolypropylene ezinegwebu zinokusebenza kakuhle kunye nethemba lokusetyenziswa, kodwa uphuhliso lobugcisa lunzima kakhulu.Okwangoku, akukho mveliso yamashishini anxulumeneyo eTshayina.Ubuchwephesha obuphambili buxhomekeke kwizandla ze-JSP kunye ne-KANEKA.
