Zita rekuti "Ini" ndiLignin.

Iyo "chirimwa skeleton" ye "ini"

Muzvakasikwa, "Ini" ndinogara ndichigara pamwe chete nemheremalose uye hemicellose, ndichishanda pamwechete kuvaka schenleton. Vanhu vanondivigira mumhando nhatu:Hardwood Lignin, Conifer Ligninuyeherbal lignin. Kazhinji, "Ini" ndinogoverwa nguva dzose mumaruva masero. Kusvinwa kwe "Ini" ndiri mukwende wakakwira Sechikamu chetatu chakakura organic sosi mune zvakasikwa, kunyange "ini" ndakashandiswa nevanhu zviuru zvemakore zvakapfuura, haina kuitwa zvakanyanya kusvika zvino.

"Ini" mukugadzirwa kwemaindasitiri

MuChina, "Ini" ndinogona kuteedzerwa kudzokera kune kugadzirwa kwepepa. " Chinangwa chekupururudza uye mapepa ekurongedza ndewe kuchengetedza cellulose uye hemicellulose uye bvisa "ini". Iyo Midziyo Yakasarudzika Inosanganisira Hondo yegorosi, tsanga yemupunga, tsanga yemuchero, etcems yeiyo "ini" " yemasango azova dambudziko rakakura muzvipfuyo zveMitoro marara kurapwa.

Pane zvinhu zviviri zvikuru zvemaindasitiri ekunze ane hukama. Kune rimwe divi, "ini" ndiri mudondo rakaparadzaniswa kubva kuHydrolysis yehuni; Kune rimwe divi, inovanzika padambudziko remvura remvura yepaindasitiri yepepa. Nyika dzekunze dzakagadzira seti yehuni-yekugadzira marara ekurapa ekurapa maitiro maitiro. Kutanga, iyo "Ini" ndiri mumvura ine tsvina yakagadzirwazve neAlkali, uyezve zvakare yandinoshandiswa pakurwisirwa uye simba. Izvi zvinowanikwa kune yakakura kukura pahwaro hwekugadzirisa dambudziko rekusvibisa. Inoponesa simba.

Kuparadzaniswa uye kubviswa kwe "i"

Kuti tivandudze kushandiswa kwakabudirira kwe "Ini" Ini ", masayendisiti kumba uye kunze kwenyika zviri kushingairira kudzidza kuparadzaniswa uye kubviswa kwe" Ini ". Mukugadzirwa kwemaindasitiri, isu tinowanzo kupatsanurwa uye kubviswa kana cellulose ichishandiswa. Kubva pamaonero ekutsvaga kwesainzi, vanhu vanoparadzaniswa uye vanobvisa "Ini" kuti ndiwane samples nekuchena kwakanyanya, kana samples nezvivakwa zvakananga nezvivakwa.

Kazhinji, kune marudzi makuru maviri ekuparadzaniswa kwe "Ini": Imwe ndeyekunyungudika zvikamu kunze kwangu mumuviri wehurombo, uye wozoparadzanisa zvisina kufanira "ini". Muenzaniso chaiwo uri mugondo hydrolysis indasitiri. Chinhu chakanyungudika hydrolyzed kuti glucose pasi pechiito cheAcid, uye "ini" ndakaparadzaniswa sevanhu vakasara ve hydrolysis; Imwe yacho ndeyekunyepedzera iyo "Ini" mumuviri wezvirimwa, zvinoparadzanisa zvimwe zvinhu uye ndobva ndareva kuti ndiwane "ini".

Rudzi rwekupedzisira rwekuparadzanisa runozivikanwa mukupururudza kwepepa. Iyo yakazadziswa mumhando mbiri dzenzira dzekuparadzanisa. Iyo yekutanga "Ini" iSufonated muhomwe-solubleLignosulfonate, wobva abatwa nemukaka wenziyo, "Ini" ndingadai ndakaratidzwa; Iyo yekupedzisira yakabikwa nehurefu caustic soda pakupisa kwakanyanya, kana akachekwa souswa kana gorosi souswa. Chinja iyo "Ini" muAlkaline "i"

"Hunhu hwe" katatu "" ini "uye hupfumi hwakawanda

"Ini" ndi "polyphenol matatu-dimensional network network polymer ine phenylpropane seyakagadzirirwa chimiro. Iyo ine hunhu hwenzatu (iyo, zvitatu zvakakosha zvimiro): Guaicyl chimiro, syringen chimiro uye p-hydroxyphanyfenyl chimiro. Ini kuumbwa kwezvinhu zvinosiyana nemhando dzezvidyarwa uye nzira dzekuparadzanisa.

Kune akawanda mashandiro emapoka e "Ini" (Zvinonhuwirira mapoka, zvidhori mapoka, mapoka emapoka, mapoka akapetwa mapoka maviri. "Kuti uwane akasiyana emakemikari maitiro, akadai se: oxidation, kuderedza, hydrolysis, alopholysis, acidolysis, photlysis, acylation, alkylation, nitration, otheration, sulfonation, polycononsation kana graft copolymerization.

Iyo resin yakarongedzwa ne "Ini" sezvo zvinhu zvakaburitswa zvakaderera mumutengo pane zvimisikidzwa zvinoitwa mukugadzirwa kwehuwandu hwakaumbwa, uye ine imwe kukosha kwemaindasitiri. MuLigninLATEX CO-YEMAHARA ne "Ini" uye Natural Raber Latex, "Ini" iite seganda rekusimbisa, nokudaro kutsiva kabhoni kudhura uye kuderedza mutengo wezvinhu zvigadzirwa zveRabha. "Ini" ndinogona kushandiswawo sechinhu chakabikwa chekugadzirwa kwemakemikari emafuta ekuvandudza mafuta ekugadzirisa mafuta uye mafuta emafuta emifuta emafuta.

Mukuwedzera, "Ini" ndinokwanisa kushandiswawo senhau, fetiraiza inowedzera, lefficidide yakadzivirirwa, zvirimwa zvekurima zvinodzora zvesainzi, ini ndichave nemikana yakawanda uye yakawanda yekuratidza hunyanzvi hwangu.
