Nhamba dzinoverengeka dzinokosha dzeRabha

1. Rubber

Tsanangudzo yakagamuchirwa yakagamuchirwa rabha inotaurwa kubva ASTM D1566 (American Society yekuedza uye Zvishandiso).
Tsanangudzo:
Rabha Ko zvinhu zvinokwanisa kukurumidza uye zvine simba kupora mushure mekushora kukuru, uye unogona kushandurwa ( Vulcanized ). Iyo yakagadziridzwa rabara ndeyechokwadi Insoluble (asi Schellllable ) mukubira Benzene, methyl ethyl ketone , kana ethanol-toluene Solvent musanganiswa.
Pamhepo tembiricha (18-29 ° C), kana chidimbu chakatsanangurwa rubber kune kaviri urefu hwayo hwekutanga uye nekubatwa kweminiti imwe, padzisunungure mukati meminiti imwe chete kusvika pane imwe nguva yakareba kusvika pa1.5
Chinhu chinoratidzira izvi hunhu hunotsanangurwa se rabha.

Zvinyorwa:

Rabha chinhu chine chekuita chaicho application uye kugadzirisa zvivakwa uye ndezvekirasi ye Organic Polymer Zvigadzirwa.

Rabha kuratidzwa Yakakwirira Elasticity kumhepo tembiricha.

Izwi rekuti "rakajeka" rinoreva kugona kwayo Vulcanization.

Vulcanized Rubber ndizvo Insoluble asi Schellllable mune solvent.

2. Raw Rubber

Mbichana mbichana zvinoreva Undlucanized Rubber izvo hazvina kuiswa pamwe nekuwedzera uye haasati asati adzivirira kuyambuka . Zvinowanzoitika mutsara macromolecules kana Barned Linear Polymers uye ndizvo nyura mukati organic solventes.

Mbichana mbichana inonyanya kushandiswa kuburitsa zvakasiyana Isiri-Vulcanized Rubber zvikamu , zvakaita se Nguva pfupi Kuiswa Gaskets, Majoini asina kujairika , uye Rabara inokara maratidziro.
Zvigadzirwa izvi zvinoratidzira zvakanaka Plasticity uye Kudzorera , asi yakaderera kupisa kupokana uye Simba reMuchina , kuvaita kuti vakwanise pre-kugadzirisa kana semi-apedzwa matanho yekugadzira rabha.

3. Rabha Rubpound (yakasanganiswa rabara)

Rabha compound (Compound Rabara) zvinoreva mbichana mbichana izvo zvakasanganiswa nevari kusiyaniswa Vamiriri vanowedzera asi haasati adzingwa Vulcanization.
Zvakajairika kuwirirana vamiririri vanosanganisira Vulcanizizizizing vamiririri, accelerators, vatambi, kusimbisa mafirita , uye Antioxidants.

Rabha compound inoshanda sekiyi Intermediate zvinyorwa Nekuti Isiri-Vulcanized Rubber zvikamu , uye inogona zvakare kuve mberi Vulcanized kuumba Vulcanized Rubber zvikamu Nepamusoro Elasticity, Kuganhurira Kuparadzanisa , uye kusimba.

4. Vulcanized Rubber

Vulcanized Rubber zvinoreva Rabha compounds izvo, pasi zvakananga tembiricha, kumanikidza , uye nguva , pasi pe Crosslinking Reaction , Shanduko mutsara macromolecules a matatu-dimensional network dhizaini.
Zvinowanzo Insoluble Mune solvent uye inoratidzira yakanaka kwazvo Simba reMuchina, Elasticity, abrasion kuramba , uye kupisa kupokana.

Rudzi urwu rwe rabha inoshandiswa zvakanyanya mukugadzirwa kwezvakasiyana-siyana Vulcanized Rubber zvikamu , zvakaita se Zvemotokari Vibration Damper, Zvisimbiso Zvemafuta, O-mhete, tambo yetambo , uye Maindasitiri ekuisa maindasitiri zvigadzirwa.
Mukupesana ne, Isiri-Vulcanized Rubber zvikamu inonyanya kushandiswa mukati process shanduko kana dziviriro yenguva pfupi Zvikumbiro, uye hazvigone kutsungirira-refu-kufumurwa kupisa kwakanyanya, kumanikidza kwepamusoro , kana nharaunda dzemakemikari.

Tsanangudzo yakagamuchirwa yakagamuchirwa rabha inotaurwa kubva ASTM D1566 (American Society yekuedza uye Zvishandiso).
