Urea Formaldehyde Uf Adhesive Resins no ka laau

4. Nā hana kūpono
He kūpono ka resin Urea-formaldehyde no nā kaʻina hana like ʻole e like me ka uhi ʻana a me ka hoʻoheheʻe ʻana, hāʻawi i ke kākoʻo no ka hana ʻana i nā huahana like ʻole.
5. Noi
E like me ka mea i hoʻohana nui ʻia i ke kāpili lāʻau.urea-formaldehyde resinhoʻohana nui ʻia i ka hoʻopaʻa ʻana i ka lāʻau, plywood, laminates, a me ka ʻohe a me nā huahana lāʻau. No ka laʻana, hoʻohana ʻia ia e hana i nā pūpū lāʻau o nā papahele, nā lako, nā pahu pahu, nā lako lole, a me nā mea pono hale.
1. Hoʻonui i ka pale wai o ka urea-formaldehyde resin adhesive: Ma ka hoʻohui ʻana i nā mea hoʻohui cross-linking e like me ka alumini sulfate a me ka alumini phosphate, hiki ke hoʻomaikaʻi maikaʻi ʻia kona kūpaʻa wai.
2. E hoʻomaikaʻi i ka pale ʻana i ka wā kahiko: ʻO ka hui ʻana i kekahi mau resins thermoplastic i loko o nā mea hoʻopili resin urea-formaldehyde hiki ke hoʻomaikaʻi nui i ko lākou kūpaʻa ʻelemakule.
3. E ho'ēmi i ka formaldehyde maʻiʻo: Ma ka hoʻololiʻana i ke kaʻina hana synthesis, e ho'ēmi i ka ratio molar o ka formaldehyde i ka urea, a iʻole ka hoʻohuiʻana i nā mea hoʻopili formaldehyde (e like me ka urea, melamine, a me nā mea'ē aʻe), hiki ke hoʻokōʻia ke kumu o ka ho'ēmiʻana i ka formaldehyde i loko o ka urea-formaldehyde resin adhesives.
Kūʻai aku ʻo Aojin Chemical i nā resins urea-formaldehyde kiʻekiʻe me nā kūlana kiʻekiʻe o ka huahana. Hoʻolako i ka ʻoihana lako a me ka ʻoihana papa. E kiʻi i ke kumukūʻai maikaʻi loa no ka resin urea-formaldehyde i kēia manawa, e hoʻopili koke iā Aojin Chemical!
