Lub zog ntsuab yog qhov hnyav heev thaum nws los tiv thaiv kev tawg thaum lub sij hawm thib ob ntawm kev tsim cov log tsheb los yog thaum nws tuaj yeem tiv thaiv kev tawg ntawm ib qho nyuaj extruded profile vim muaj zog gravitational.

1. Kev cuam tshuam ntawm molecular hnyav

Feem ntau hais lus, qhov siab dua qhov hnyav molecular ntawm elastomer xaiv, Green lub zog ntau dua. Nyob rau hauv cov ntaub ntawv ntawm SBR, ib tug siab nruab nrab molecular hnyav yog siv, tab sis siab heev ib tug molecular hnyav yuav ua tau rau lwm yam teeb meem.

2. Strain-induced crystallisation

Adhesives nrog strain-induced crystallisation zoo li muaj Green lub zog siab.

3. Ntuj roj hmab

Ntuj roj hmab muaj lub siab Green lub zog. NR muaj Green lub zog siab vim qhov tseeb tias nws crystallises thaum ncab. Cov kua nplaum ntuj nrog cov ntsiab lus siab dua ntawm fatty acid ester pawg muaj ntau dua Green lub zog vim muaj ntau dua ntawm crystallisation nyob rau hauv nro, feem ntau nrog cov ntsiab lus tsawg kawg nkaus ntawm fatty acid ester pawg ntawm txog 2.8 mmol / kg.

4. Thaiv cov polymers

Lub xub ntiag ntawm me me ntawm block styrene hauv random copolymer SBR adhesives tuaj yeem muab cov nplaum nplaum zoo Green lub zog.

5. Semi-crystalline EPDM

Kev xaiv ntawm semi-crystalline EPDM nrog cov ntsiab lus ethylene siab tuaj yeem muab cov nplaum zoo Green lub zog ntawm chav tsev kub.

6. Metallocene-catalyzed EPDM

Lub chaw ua haujlwm ib leeg txwv geometry metallocene catalyst thev naus laus zis ua rau muaj cov ntsiab lus ethylene siab EPDM ntawm qhov loj. Qhov no EPDM nrog cov ntsiab lus ethylene siab muaj Green lub zog siab. Nrog rau cov thev naus laus zis no cov ntsiab lus ethylene tuaj yeem tswj tau thiab Green lub zog ntawm EPDM tuaj yeem nce ntxiv.

7. Molecular hnyav faib

NBR cov tebchaw nrog qhov nqaim molecular hnyav faib muaj Green lub zog siab.

8. CR

High Green lub zog tuaj yeem tau txais los ntawm kev xaiv ceev ceev crystallising neoprene. Qhov sib ntxiv ntawm SBR nrog cov ntsiab lus siab styrene rau CR tuaj yeem txhim kho Green lub zog.

Ntawm cov ntau yam ntawm neoprene, Hom T neoprene muaj qhov zoo tshaj plaws tiv thaiv lub cev qhuav dej thiab deformation, piv txwv li lub siab tshaj plaws Green lub zog, ua raws li hom W. Hom G neoprene muaj qhov phem tshaj Green lub zog.

9. Polytetrafluoroethylene

Teflon additives txhim kho Green lub zog ntawm cov nplaum.

10. Carbon dub

Cov pa roj carbon dub nrog thaj chaw siab thiab cov qauv siab txhim kho Green lub zog ntawm cov roj hmab. n326 feem ntau siv rau hauv cov log tsheb hlau npog vim nws muab cov roj hmab siab Green lub zog thaum ua kom cov viscosity tsawg txaus rau cov hlau nkag mus.

Rau qhov zoo Green lub zog, cov pa roj carbon dub nrog cov qauv siab thiab qhov chaw qis qis yuav tsum tau siv. Qhov no yog vim hais tias ib cheeb tsam tsawg carbon dub tso cai rau lub ntim ntau dua, uas nyob rau hauv lem ua rau Green lub zog.

11. Sib tov

Hauv cov txheej txheem sib xyaw, yog tias cov elastomer dhau-plasticised, Green lub zog ntawm cov compound yuav raug txo.
