He aha nā ʻokoʻa ma waena o nā emulsion PTFE i hana ʻia e nā kaʻina polymerization like ʻole (polymerization suspension a me ka polymerization dispersion)?

Hoʻolauna ʻia e a ʻO ka Teflon High-Temperature Fabric Manufacturer i nā ʻokoʻa ma waena o nā Emulsions PTFE i hana ʻia e nā kaʻina hana polymerization like ʻole (Suspension Polymerization a me Dispersion Polymerization)

I. Ka wehewehe mua o na manao

I ka hana ʻoihana, ʻaʻole hiki i ka polymerization hoʻokuʻu ke hana pololei i ka emulsion PTFE. ʻO ka emulsion PTFE maoli (ka hoʻopuehu) ua hana wale ʻia e ka dispersion polymerization (ʻo ia ka emulsion polymerization). Hoʻomaopopo ʻo Jiangsu Teflon High-Temperature Fabric Manufacturer i loaʻa i ke kālepa ʻo 'suspension-method PTFE emulsion' he wai hoʻokuʻu i hana ʻia e ka hoʻopuehu ʻana i nā micropowders resin hoʻokuʻu-polymerized. ʻOkoʻa nā mea ʻelua, mai ke ʻano ʻāpana a i nā noi hoʻohana hope.

II. Hoʻopuehu Polymerization: Primary PTFE Emulsion

1. ʻO ka moʻokalaleo a me ke kūpaʻa

He spherical maikaʻi nā ʻāpana, i hana ʻia e ka hoʻohui ʻana o nā ʻāpana mua (0.05-0.5 μm) i nā ʻāpana lua me ka nui o ka 0.1-0.3 μm a me ka puʻunaue haiki loa. Hāʻawi ʻia ke kūpaʻa e nā surfactants perfluorinated (PFOA alternatives) i hoʻohui ʻia i ka wā polymerization. Hiki ke kūpaʻa ka ʻōnaehana colloidal me ka ʻole o ka stratification no nā makahiki a hōʻike i ke kūpaʻa maikaʻi ʻana i ka ʻoki mīkini.

2. Kaumaha Molekala a me na waiwai hana kiʻiʻoniʻoni

He kiʻekiʻe loa ka paona molekala (a hiki i nā miliona), me ka crystallinity ma mua o 94% a me ka mana fibrillation ikaika loa. Ma hope o ka uhi ʻana, koi ʻia ka sintering kiʻekiʻe ma kahi o 380 ° C, i ka manawa e hui ai nā ʻāpana i loko o kahi kiʻiʻoniʻoni hoʻomau, paʻa a paʻakikī me nā waiwai anti-corrosion a me nā waiwai ʻole.

3. ʻO ka hana maʻamau a me nā noi

Hoʻopili ʻia ka hana ʻana i ka extrusion, impregnation, a i ʻole ka uhi ʻana i ukali ʻia e ka sintering. ʻO nā noi maʻamau e pili ana i nā uhi kīʻaha non-stick, impregnation o nā membrane kūkulu hale fiberglass, microporous ePTFE membranes (hanu a wai ʻole), a me nā kiʻiʻoniʻoni capacitor kiʻekiʻe.

III. Hoʻokuʻu ʻia ʻo Polymerization Micropowders: Hoʻokuʻu ʻia i ka wai (Ke kuhi hewa ʻia e like me ka Emulsion)

1. ʻO ka moʻokalaleo a me ke kūpaʻa

E like me ka mea i hōʻike ʻia e Jiangsu Teflon High-Temperature Fabric Manufacturer: Hoʻopuka ʻia nā ʻāpana ma ka wili ʻana a me ka ʻoki ʻana i nā pellets suspension-polymerized, ka hopena i nā ʻano polyhedral irregular me nā ʻāpana nui mai ka 2 a hiki i ka 20 μm a me ka hoʻohele ākea. ʻAʻole kūpaʻa ka ʻōnaehana thermodynamically a hiki i ka sedimentation a me ka stratification. Pono e hoʻohui ʻia nā surfactants maʻamau a me nā mea mānoanoa e like me ka xanthan gum a me cellulose ethers i mea e hoʻopaneʻe ai i ka sedimentation, a pono e hoʻoulu ʻia ma mua o ka hoʻohana ʻana.

2. Kaumaha Molekala a me na waiwai hana kiʻiʻoniʻoni

Hiki ke hoʻololi ʻia ke kaumaha molekala i kahi ʻano haʻahaʻa (ʻumi kaukani a i nā haneli haneli), me ka brittleness nui aʻe a nāwaliwali loa ka mana fibrillation. Ma hope o ka uhi ʻana, pono wale ka maloʻo ambient a haʻahaʻa paha e hana i kahi papa lubricating maloʻo; ʻaʻole hiki ke hoʻopaʻa ʻia i loko o kahi kiʻiʻoniʻoni.

3. ʻO ka hana maʻamau a me nā noi

Hiki ke hoʻokomo ponoʻia i loko o nā formulations a iʻole e hoʻohanaʻia e ka uhiʻana a me ka maloʻo ea. Hoʻopili nā noi i nā mea hoʻohui lubricant ʻoihana, nā mea hoʻokuʻu ʻana i ka pulu a me ka plastic mold, anti-wear and slip agents no ka inika a me ka uhi, a me ka hoʻopau wai-repellent no nā textiles.

IV. Nānā wikiwiki: Nā ʻokoʻa kumu

Kumu ʻĀpana

Nā ʻāpana polymerization hoʻopuehu: hana ʻia i loko o kahi i loko o nā ʻano pōʻai ma o ka dispersion polymerization;

Nā ʻāpana ʻano hana hoʻokuʻu: lepo mai ka resin nui i loko o nā granule like ʻole.

Nui ʻāpana

ʻO ka emulsion hoʻopuehu maka: 0.1-0.3 μm me ka hāʻawi ʻana i ka nui o nā ʻāpana haiki;

ʻO ka wai hoʻomaha: 2-20 μm me ka hāʻawi ʻana i ka nui o ka nui.

Mea hoʻopaʻa

Hoʻopuehu polymerization: perfluorinated surfactants;

Ka wai hoʻomaha: nā surfactants maʻamau me nā mea mānoanoa.

Waiwai hana kiʻiʻoniʻoni

Hoʻopuehu polymerization: hana mau, paʻakikī kiʻiʻoniʻoni ma hope o ka sintering wela kiʻekiʻe;

ʻO ka wai hoʻomaha: ʻaʻole hana kiʻiʻoniʻoni, hāʻawi wale i kahi papa lubricating maloʻo.

Nā noi nui

ʻO ka polymerization hoʻopuehu: nā pale non-stick, anti-corrosion linings, nā kiʻiʻoniʻoni hana;

ʻO ka wai hoʻokuʻu: nā mea hana anti-friction, nā mea hoʻokuʻu, nā mea hoʻohui pale pale no ka inika.

Ka hopena mai Jiangsu Teflon High-Temperature Fabric Manufacturer: Inā makemake kāu noi i ka impregnation, coating sintering, a i ʻole ka hoʻokumu ʻana i ke kiʻiʻoniʻoni, pono ʻoe e koho i ka emulsion PTFE mua i hana ʻia e ka dispersion polymerization. Inā pono ʻoe e hoʻomaikaʻi i ka lubricity, hoʻokuʻu i nā waiwai, a i ʻole ke kūpaʻa abrasion me ka ʻole o ka sintering, a laila ʻo ka hoʻokuʻu wai i hana ʻia mai nā micropowders suspension-polymerized he koho kūpono.

Hāʻawi ʻia ka ʻike ma luna e Jiangsu Aokai New Material Technology Co., Ltd.

Inā makemake ʻoe e aʻo hou aʻe e pili ana i nā kikoʻī kikoʻī, nā hiʻohiʻona noi, a me nā hoʻoponopono hoʻoponopono no kā mākou huahana holoʻokoʻa-me nā lole wela kiʻekiʻe ʻo Teflon, nā lipine wela kiʻekiʻe Teflon, nā kāʻei mesh wela kiʻekiʻe ʻo Teflon, mīkini hoʻopaʻa ʻana i nā kāʻei maʻemaʻe, ʻaoʻao hoʻokahi ʻaoʻao PTFE lole, kiʻekiʻe-mehana a me nā lole fiberglass kiʻekiʻe. e hoʻokaʻaʻike mai iā mākou ma o kēia:
