Kubva kuCashew Nuts Shells kusvika kuHigh-Value Cardanol: Molecular Distillation Inotsigira Kucheneswa kweNatural Phenolic Raw Materials

Zvichienderana nemakemikari egirini, zvinhu zvakagadzirwa nebio, uye kudiwa kuri kukura kwekushandiswa kwezviwanikwa zvinogona kushandiswazve, kushandiswa kwakakosha kwezvinhu zvinobva mukugadzira cashew kuri kukwezva kutariswa kuri kuwedzera. Sechitubu chakakosha chemvura chinotorwa kubva mumagoko e cashew nut, mvura ye cashew nut shell iri kushandurwa kubva muchibereko chekurima kuita chinhu chakakosha che phenolic chekugadzira machira, ma resin, manamati, uye zvinhu zvakasanganiswa.

Mvura yeCashew nut shell, inozivikanwawo seCNSL, musanganiswa wechisikigo wephenolic unowanikwa nekudzvanya kana kubvisa maganda ecashew nut. Maumbirwo awo anosiyana zvichienderana nenzira yekuburitsa uye maitiro ekupisa. Natural CNSL inowanzova neanacardic acid, cardanol, cardol, uye huwandu hushoma hwemethyl cardol. Mushure mekurapa kupisa kwakanyatsogadzirwa, anacardic acid inogona kubudiswa mucarboxylation uye kushandurwa kuita cardanol, zvichiwedzera zvakanyanya huwandu hwecardanol muCNSL yehunyanzvi.

Cardanol chinhu chakakosha chinowanikwa kuburikidza nekubvisa, kupatsanura, uye kucheneswa kwemvura yeganda re cashew nut. Imusanganiswa we phenolic wechisikigo une chimiro chemakemikari chakasiyana. Molekyuru yayo ine benzene ring, polar hydroxyl group, uye C15 unsaturated long carbon chain yakabatana panzvimbo yayo. Chimiro ichi chinopa cardanol mabhenefiti akasiyana-siyana ekushanda: benzene ring inobatsira kuvandudza kupisa; hydroxyl group inopa kugona kuri nani kwemvura uye kuita zvinhu zviri nani panzvimbo dzinosangana; uye C15 unsaturated long chain inobatsira pakuchinjika kwakanaka, hydrophobicity yakanaka, low permeability, uye kuzviomesa.

Nekuda kwehunhu uhwu, cardanol inogona kushandiswa sechinhu chinotsiva kana chinotsiva chikamu chephenol mukugadzira epoxy curing agents, phenolic resins, phenolic laminates, copper-clad laminates, HB boards, surfactants, coating-grade phenolic resins, adhesives, friction materials, nezvimwe zvigadzirwa zvemakemikari zvakagadzirwa nebio-based. Kana ichienzaniswa nezvinhu zvepetrochemical phenolic raw, cardanol inobva muzviwanikwa zvemiti zvinogona kushandiswazve uye inosanganisa mabhenefiti ekushanda negreen material value, ichiipa mukana wakasimba mukugadzirwa kwemakemikari ane kabhoni shoma uye kugadzirwa kwezvinhu zvinogara kwenguva refu.

Zvisinei, kuwana cardanol yemhando yepamusoro kubva mumvura ye cashew nut shell nenzira yakagadzikana uye inoshanda hazvisi nyore. CNSL imhando yemafuta echisikigo anofashaira zvakanyanya, anonzwa kupisa, uye ane viscosity yakanyanya. Mumaitiro echinyakare ekudiridza, inogona kusangana nematambudziko akadai senguva refu yekupisa, kusviba kwemavara, kubika, uye kupatsanurwa kwezvikamu zvisina kugadzikana. Mukugadzirwa kwemaindasitiri, kudzora zvisina kunaka kwevacuum grade, nzira yekupisa, nguva yekugara, uye kushanda zvakanaka kwe condensation zvinogona kukanganisa zvakananga kuchena, ruvara, uye mashandiro ekushandisa kwe cardanol.

Kunyungudutsa kwemolecular film short path molecular distillation kunopa mhinduro yakakodzera yekuchenesa rudzi urwu rwezvinhu zvechisikigo zvephenolic. Mushure mekunge zvinhu zvapinda mu molecular distillation system, wiper inogadzira firimu rakatetepa rakafanana pamadziro emvura. Mumamiriro ekunze akasimba, zvikamu zvakapfava nezvikamu zvinorema zvinogona kupatsanurwa zvinobudirira. Kana zvichienzaniswa ne distillation yechinyakare, molecular distillation inopa nguva pfupi yekugara kwezvinhu, tembiricha yekushanda iri nyore, njodzi yakaderera yekuora kwekupisa, uye kugona kuri nani kwekugadzirisa. Yakakodzera zvakanyanya kupatsanura nekuchenesa zvinhu zvinofashaira zvakanyanya, zvine viscosity yakawanda, uye zvinonzwa kupisa. Masisitimu ese ari maviri e distillation emolecular anogona kugadzirwa semhando yegirazi, mhando yesimbi isina ngura, imwe-nhanho, maviri-nhanho, akawanda-nhanho, uye yakazara jaketi otomatiki yekudya uye kuburitsa otomatiki zvichienderana nehunhu hwakasiyana hwezvinhu, zvichisangana nezvinodiwa zvakasiyana kubva mukutsvagisa kwerabhoritari kusvika pakuwedzera kwepilot uye kugadzirwa kunoramba kuripo kweindasitiri.

Padanho rekuongorora nekuvandudza murabhoritari, makambani anogona kutanga ashandisa girazi rakapukutwa firimu pfupi nzira yemasero distillation system kuita bvunzo diki paCNSL samples. Izvi zvinobatsira kuona kuyerera kwezvinhu, kuchinja kwemavara, kushanda kwechikamu chekupatsanurana, uye kugadzikana kwevacuum, ukuwo vachikurumidza kugadzirisa maparamita akadai setembiricha, dhigirii revacuum, chiyero chekudyisa, uye mamiriro ekunyorovesa.

Padanho rekuwedzera, michina yekunyudza simbi isina ngura inogona kusarudzwa kuti ivandudze kushanda kwekupisa uye kugona kwayo kugadzirisa. Danho iri rakakodzera kusimbisa kudyiswa nguva dzose, kuburitsa mvura nguva dzose, uye kugadzikana kwekushanda kwenguva refu.

Kumapurojekiti ekugadzira maindasitiri, sisitimu iyi inogona kuve nekupisa kwakazara nejaketi, kudya nekuburitsa otomatiki, kuburitsa pombi yegiya, mayuniti evacuum akawanda, dziviriro yemusungo unotonhora, uye mamodule ekutonga otomatiki. Magadzirirwo aya anobatsira kuderedza njodzi dzekuvharika, kubikwa, uye kushanduka kwevacuum, ukuwo zvichivandudza kugadzikana uye kushanda zvakanaka kwekugadzirwa kwecardanol.

Kubva kurutivi rwekushandisa, cardanol inogona kushanda kwete chete muma coatings, epoxy curing agent, phenolic resin, uye copper-clad laminate industries, asiwo inowedzera kusvika kuma surfactants, oilfield chemicals, rabha additives, friction materials, glues, uye bio-based polymer materials. Sezvo kudiwa kwemusika kuchiwedzera kwezvinhu zvine VOC shoma, zvinogona kudzokororwa, zvinoramba ngura, uye zvinoshanda zvakanyanya, kukosha kwecardanol muindasitiri kunotarisirwa kuramba kuchikura.

Pamusoro pekucheneswa kwecardanol kubva kuCNSL, mafuta echisikigo akafanana, zvinotorwa mumiti, zvinhu zvinoshanda zvemumiti, mafuta ehove eOmega-3, vhitamini E, mafuta eMCT, biodiesel, nemamwe mapurojekiti anogonawo kugadzira mitsara yakakwana yekugadzira kuburikidza nekubvisa, kupwanya, kunyorovesa mamorekuru, uye maitiro ekuchenesa. Kune mamwe mapurojekiti echikafu, emishonga, ezvekudya, uye ezvehupenyu, tekinoroji yekuomesa nechando inogonawo kusanganiswa kuti igare yakasimba, kuomesa nekupisa kwakaderera, uye kudzivirira zvinhu zvinoshanda, zvichiwedzera kuwedzera mamiriro ekushandiswa kwezvinhu zvakasikwa. Midziyo yekuomesa nechando inoshandiswa zvakanyanya mukugadzira chikafu, biopharmaceuticals, kugadzira chikafu nehutano, uye kutsvagisa kwezvehupenyu, uye inogona kusanganiswa nemasisitimu ekugadzira mamorekuru kuti ivake mhinduro yakakwana yemaitiro.

Kune mapurojekiti ekuchenesa CNSL-kubva-ku-cardanol, BOTH inogona kupa mhinduro dzakagadzirwa dzemamorekuru dzakagadzirwa zvichienderana nehunyanzvi hwemutengi hwezvinhu zvakabikwa, kuchena kwakanangwa, kushandiswa kwekupedzisira, uye kugona kunodiwa. Kubva pakusimbiswa kwerabhoritari uye kuwedzera kwekuyedza kusvika kumitsetse yekugadzira maindasitiri, BOTH inobatsira vatengi kupfupisa nguva yekuvandudza maitiro, kuvandudza kushanda kwekuparadzanisa, uye kuvaka hwaro hwakasimba hwekugadzira kukuru mune ramangwana.

Kana uri kuronga chirongwa chekuchenesa mvura ye cashew nut shell kuti ugadzire cardanol, zvinokurudzirwa kuti usimbise zvinotevera pachine nguva:

Chiyero chekugadzira chauri kugadzira parizvino ndechei?

Uri kuronga kuwedzera kugadzirwa kwezvinhu mune ramangwana here?

Unyanzvi hupi hwekugadzirisa hwaunoda, hwakadai se kg/h, kg/day, kana ton/day?

Bata mainjiniya ese ari maviri kuti uwane sarudzo yemuchina wakagadzirirwa iwe uye mhinduro yakakwana yekuchenesa cardanol kubva mumvura ye cashew nut shell.
