Fa'aaogāina ole Phenol ile Palasitika ma Mea Fa'akomepiuta
Phenolic resin o se tasi o talosaga muamua ophenol i le fanua o mea polymer. Phenolic resins o palasitika thermosetting e faia e le condensation o phenol ma formaldehyde i lalo o le gaioiga a acidic po o alkaline catalysts. O lo'o iai a latou mea e sili ona lelei fa'a'ese'ese, maualuga le vevela, ma fa'a'ele'ele'ele'ele, ma fa'aaogaina lautele i mea fa'amama, fa'alavalava, fa'apipi'i, fa'apea fo'i ile va'alele ma fale ta'avale. Phenolic resins o loʻo faʻaaogaina foi i le gaosiga o laminates, paipa, ma oloa palasitika thermosetting, o loʻo avea o se mea e manaʻomia i le pisinisi vailaʻau.
Fa'aaogāina ole Phenol ile Pharmaceuticals ma Fine Chemicals
O le Phenol fo'i e iai sona taua tele i le falema'i vaila'au, e masani ona fa'aaogaina e avea o se vaeluagalemu i le tu'ufa'atasiga o vaila'au eseese. Mo se faʻataʻitaʻiga, Paracetamol (faʻapitoa foi o le acetaminophen) o se vailaʻau faʻamaʻi masani ma analgesic e manaʻomia ai le phenol e fai ma mea faʻapitoa i le taimi o le faʻaogaina. O le Phenol o loʻo aʻafia foi i le gaosiga o vailaʻau faʻamaʻi ma vailaʻau antineoplastic. I tua atu o vailaʻau, e faʻaaogaina le phenol i le sauniuniga o vailaʻau faʻamaʻi ma faʻasao, e pei o vaifofo phenol faʻaaogaina mo le faʻamaʻaina i falemaʻi ma meaʻai.
Fa'aaogāina ole Phenol ile Alamanuia ole Pesticide
Ole alamanuia ole vailaau fa'atosina o lo'o fa'atusalia ai se isi vaega taua ole fa'aoga mo le phenol. Ole vaega ole hydroxyl ile fausaga ole phenol e mafai ona fa'afeagai ma vaega vaila'au eseese e maua mai ai vaila'au fa'ama'i fa'ama'i ma a'afiaga ole herbicidal. Phenolic derivatives e masani ona faʻaaogaina i le tuʻufaʻatasia o fungicides, herbicides, ma insecticides. Mo se faʻataʻitaʻiga, Mancozeb, o se fungicide taʻutaʻua, e manaʻomia le phenol e avea ma mea faʻavae i lona gaosiga. O fa'aoga a le Phenol i le fa'alapotopotoga o vailaau fa'ato'aga e saofagā e le gata i fua o fa'ato'aga ma le fa'aleleia atili o le lelei ae fa'apea fo'i le lagolagoina o atina'e fa'ato'aga gafataulimaina.
Fa'aaogāina ole Phenol ile Vali ma mea manogi
E taua tele le sao ole Phenol ile pisinisi vali. E ala i le faʻaofiina o vaega vailaʻau eseese, e mafai ona liua le phenol i ni vailaʻau eseese, e pei o le azo dyes ma le anthraquinone dyes, lea e faʻaaogaina tele i le ie, pepa, ma fale teuteu. E a'afia fo'i le Phenol i le gaosiga o mea manogi ma mea teuteu. Mo se faʻataʻitaʻiga, o le phenol ethoxylates e masani ona faʻaaogaina vaega manogi o loʻo maua i mea manogi ma vailaʻau.
Isi Avanoa Talosaga
E maua fo'i e le Phenol le tele o le fa'aoga i mea fa'afefe mu, polyurethanes, pa'u, ma mea fa'apipi'i. Phenolic derivatives o loʻo faʻaaogaina e fai ma mea mataʻutia mo faʻamaʻi afi, faʻaleleia le faʻamalosia o le afi o mea. E mafai foi e le Phenol ona tali atu i le isocyanates e fausia ai mea polyurethane, o loʻo i ai le tele o faʻaoga i le insulation, cushioning, ma le afifiina. O le eseesega o le fausaga ma le gaioiga o le phenol o loʻo faʻamaonia ai lona taua i nei vaega.
Fa'ai'uga
O le Phenol o lo'o fa'aaogaina tele i le gaosiga o vaila'au, fa'asolo atu i matā'upu fa'asaienisi meafaitino, vaila'au, vaila'au fa'ato'aga, ma vali. O ona uiga fa'a-kemikolo fa'apitoa e avea ai ma mea taua tele i le tu'ufa'atasiga o le tele o mea fa'aopoopo ma oloa. Faatasi ai ma le alualu i luma i tekinolosi ma le atinaʻeina o faiga fou, o faʻataʻitaʻiga faʻaoga ma le taua o le phenol e faʻamoemoe e faʻalautele atili, e tele sona sao i le atinaʻeina gafataulimaina o pisinisi kemisi.
