ʻO nā mea degradable kahi papa o nā mea polymer i hiki ke hoʻoheheʻe ʻia i nā mea pōʻino ma o ka hana microbial i loko o ke kaiapuni kūlohelohe, kahi mea nui i ka hoʻohaʻahaʻa ʻana i ka pollu plastic a me ka pale ʻana i ke kaiapuni. Aia ma lalo iho nā kikoʻī o kekahi mau mea biodegradable maʻamau:

1. PLA (ʻakika polylactic):

Hana ʻia mai nā kumuwaiwai mea kanu hou (e like me ka starch kulina), he plastic biodegradable.

Loaʻa iā ia nā waiwai mechanical maikaʻi, kūpaʻa wela a me ke kūpaʻa kemika, a hiki ke hana ʻia i nā huahana ma o nā kaʻina like ʻole e like me ka injection molding, extrusion and blow moulding.

Loaʻa nā noi i ka ʻoihana paʻi, ʻoihana textile, kahua lapaʻau, ʻoihana mahiʻai a me ka ʻoihana kaʻa.

2.PBAT (polybutylene terephthalate/adipic acid):

He plastic biodegradable piha me nā hiʻohiʻona o ka PBA a me ka PBT, nā waiwai mechanical maikaʻi a me ka biodegradability.

Hoʻohana nui ʻia ia i nā ʻeke kūʻai kūʻai hale kūʻai, nā pahu ʻaina awakea, kiʻi ʻāina mahiʻai, etc., me ka koi mākeke ikaika.

3. PCL (polycaprolactone):

He polymer me ka biocompatibility maikaʻi loa a me ka degradability.

Hoʻohana nui ʻia ʻo PCL i ka lāʻau lapaʻau ma muli o kona ductility nui a me ka biocompatibility maikaʻi loa.

ʻO ka hoʻomohala ʻana o ka ʻoihana plastic degradable e kū nei i nā pilikia he nui, e like me ke kumukūʻai kiʻekiʻe, nā ʻenehana ʻenehana, ka hoʻoponopono ʻana i nā pilikia a me nā keʻena lapaʻau hope ʻole. Eia nō naʻe, me ka holomua ʻenehana a me ka hoʻolaha ʻana i nā kulekele, manaʻo ʻia e hoʻohana nui ʻia nā plastic degradable i ka wā e hiki mai ana.

ʻO nā pilikia e hiki ke loaʻa i ka wā e hoʻoponopono ai i nā mea hiki ke hoʻohaʻahaʻa ʻia e like me PLA, PBAT, a pēlā aku.

1. ʻAʻole lawa ka paʻakikī a me ka ductility: No ka laʻana, ʻoiai he mau waiwai mechanical maikaʻi ka PLA, ʻilihune kona ʻano paʻakikī a lohi kona helu crystallization, e kaupalena ana i kona hoʻohana ʻana i nā noi plastics engineering.

2. puka makani hana haiki: ʻO kekahi mau mea hoʻoheheʻe ʻia e like me ka PLA, ʻaʻohe kūpaʻa wela maikaʻi ʻole a me ka puka makani hana haiki, hiki ke alakaʻi i nā pilikia i ke kaʻina hana.

3. Pilikia wai hoohehee: I ka hana ʻana i nā mea hoʻoheheʻe ʻia e like me PBAT a me PLA, ʻoi aku ka nui o ka hoʻoheheʻe ʻana ma muli o ka nui o ka viscosity o ka hoʻoheheʻe ʻana, he mea maʻalahi ia e hana i ka hoʻonui ʻia a me ka ua, ʻoiai e hoʻopili ana i ka wai hoʻoheheʻe a hoʻemi i ka hana hana.

I mea e hoʻomaikaʻi ai i ka lubricity hana, hiki ke hoʻopau ʻia kēia mau pilikia ma ka hoʻohui ʻana i ka AIDS, e like me:SILIKE SILIMER DP800, SILIKE SILIMER DP800he kōkua hana i hoʻomohala ʻia no nā mea hiki ke hoʻoneʻe ʻia, hiki ke hoʻomaikaʻi maikaʻi i ke kahe hana a me ka maikaʻi o ka ʻili o nā mea hiki ke hoʻopau ʻia.

SILIKE SILIMER DP800, high hana hoʻoponopono AIDS i hoʻomohala kūikawā ʻia no PLA, PCL, PBAT a me nā mea hiki ke hoʻopau ʻia.

SILIKE SILIMER DP800he mea hoʻohui silicone i hoʻololi ʻia me nā pono maʻamau no nā mea degradable:

Kaʻina hana:

E hoʻomaikaʻi i ka hoʻohālikelike ʻana o nā ʻāpana pauka a me ka substrate, hoʻomaikaʻi i ke kahe ʻana o nā ʻāpana, a loaʻa ka hana lubrication maikaʻi. Hiki iā ia ke hōʻemi i ka viscosity melt, hoʻemi i ka torque extruder, ke kaomi extrusion, hoʻomaikaʻi i ka hana hana o ka mea, a loaʻa ka lubricity maikaʻi.

Nā waiwai o ka ʻili:

E hoʻomaikaʻi i ka pale ʻana a me ke kūpaʻa ʻana, e hoʻemi i ka coefficient friction o ka ʻili, hiki ke hoʻomaikaʻi maikaʻi i ka manaʻo o ka ʻili o ka mea, me kahi maʻalahi.

Nā waiwai ʻē aʻe:

E mālama pono i nā waiwai mechanical piha o ka huahana, me ka hoʻopilikia ʻole i nā ʻano degradable o ka huahana.

ʻO ke koʻikoʻi o nā mea hiki ke hoʻohaʻahaʻa ʻia, ʻo ia ka hōʻemi ʻana i ka haumia o ke kaiapuni, hoʻemi i ka hoʻohana ʻana i ka ikehu, a hāʻawi i nā hopena hoʻomau. ʻAʻole hiki i nā mea biodegradable ke hōʻemi wale i ka hopena o nā palaka ʻōpala i ke kaiapuni, akā loaʻa pū kekahi mau mākeke nui a me ka hiki. ʻO ka hoʻomaikaʻi ʻana i ke kaʻina hana a me ka maikaʻi o ka ʻili o nā mea degradable kahi loulou hiki ʻole ke mālama ʻia.

Ke hana nei ʻoe i ka hana a me ka hana ʻana i nā mea degradable? inā ʻo nā hemahema o ka huahana ke kumu o ka hana ʻana i nā mea, pono ʻoe e hoʻāʻoSILIMER DP800, SILIMER DP800kūpono ia no PLA, PCL, PBAT a me nā mea hiki ke hoʻohaumia. Hiki ke hoʻohana nui ʻia e hoʻohaʻahaʻa i nā kiʻiʻoniʻoni, straws, 3D printing consumables a me nā ʻoihana ʻē aʻe.
