Mawu oyambira: Njira yopangirazinthu zapulasitikiMakamaka zimaphatikizapo njira zinayi zazikuluzikulu: Kupanga nkhungu, chithandizo chapamwamba, kusindikiza, ndi msonkhano. Pamtunda mankhwala ndi gawo lofunikira kwambiri. Pofuna kukonza ubale wolimba wa zokutirayo ndikupereka maziko abwino chifukwa chopereka, njira zochizira zisanachitike ndizofunikira kwambiri.
Kukopa kwa pulasitiki
Makamaka zimaphatikizapo kupanga chithandizo chamankhwala komanso kupangira chithandizo. Nthawi zambiri, ma pulasitiki ali ndi kuchuluka kwa crystality, portiority yaying'ono kapena yopanda polarica kapena yotsika kwambiri, komanso yotsika mphamvu, yomwe ingakhudze cholumikizira cholumikizira. Popeza pulasitiki ndi katundu wosankha, sangathe kupangidwa mwachindunji pa pulasitiki malinga ndi njira zophunzitsira zowonjezera. Chifukwa chake, pamaso pa chithandizo, kukongoletsa koyenera kuyenera kuchitika posintha luso la zokutira ndikupereka mphamvu yolumikizirana ndi mphamvu yabwino yopangira ndalama.
Kukonda Kukuna
Kudzipereka kumaphatikizapo kuchuluka kwa pulasitiki, mwachitsanzo kutsuka mafuta ndi kumasulira pamtunda, ndikuyambitsa pulasitiki, kuti athetse zitsamba za chilumbiro.
1, kuchulukitsa
Kuchuluka kwazinthu zapulasitiki. Zofanana ndi kuchuluka kwa zinthu zachitsulo, kuchuluka kwa pulasitiki kumatha kuchitika poyeretsa ndi ma soric okhazikika kapena kuchuluka kwa ma alkaline alquine okonda. Kutchinjiriza ndi ortic sodi sodi yoyenga ndikutsuka parafini, njuchi, mafuta ndi zina zotupa za pulasitiki. Kusungunuka komwe kumagwiritsidwa ntchito sikuyenera kupasuka, kutupa kapena kung'ambika pulasitiki, ndipo imakhala ndi malo owotchera, osasunthika, osakhala owopsa komanso osayaka. Mankhwala a alkaline a alkalines ndioyenera mapiritsi a alkali-osagwirizana. Njira yothetsera caustic soda, mchere wamchere ndi zochulukirapo zowonjezera. Zowonjezera zogwiritsidwa ntchito kwambiri ndizotsatira, mwachitsanzo alkylphenol polysothylene ether, yomwe siyikhala chithovu ndipo sichikhala papulasitiki.
2, kutsegula kwapamwamba
Kuyambitsa uku ndikusintha malo a pulasitiki, ndiye kuti, kuti apange magulu a polar pamtunda kapena kuti atulutse kuti zokutidwazo zitha kunyowetsedwa mosavuta komanso kutsatsa pamalo ogwirira ntchito. Pali njira zambiri zamankhwala othandizira, monga makuti makuti mankhwala a mankhwala, makisoni oxidation, ronation vapor etchting ndi crona exntudation. Chogwiritsidwa ntchito kwambiri ndi mankhwala a Crypal makutination mankhwala, omwe nthawi zambiri amagwiritsa ntchito ma acid amadzimadzi, ndipo njira zake ndi madzi ofikira 4.5% Madzi, ndi 87.5% Sulfuric acid (zoposa 96%).
Zogulitsa zapulasitiki, monga polystyrene ndi ma plucstics, zimatha kuphimbidwa mosanjika popanda mankhwala oputitsidwa. Kuti mupeze zokutira zapamwamba kwambiri, maxidation mankhwala mapiration amagwiritsidwanso ntchito. Mwachitsanzo, patatha kuchuluka, pulasitiki pulasitiki amatha kukhazikika ndi kuchepetsa ma cerim acid mankhwala. Katundu wake wamba mankhwala ali 420g / l Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Ch Chchl / l Sulfuric acid (Chitali Chachikulu 1.83). Njira yothandizira mankhwala ndi 65 ℃ 70 ℃ / 5min10min, kuchapa madzi, ndikuwuma. Ubwino wa kunenedwa ndi a acid matenda amadzi ndikuti ngakhale mawonekedwe a pulasitiki ali ndi zovuta bwanji. Choyipa ndikuti opareshoni ndi owopsa ndipo pali zovuta zowonongeka.
Kudzinyenga Kumanja
Cholinga chodzikakamiza zokutira ndikuwongolera cholumikizira cha zokutira ku pulasitiki ndikupanga chitsulo pansi pa pulasitiki. Zosangalatsa momwe zimaphatikizira: Makina opangira mphamvu, kuwongolera deration, mankhwala opangira mankhwala, chithandizo chothandizira, chithandizo chowonjezera, mankhwala ochepetsa mankhwala. Zinthu zitatu zoyambirira zikuwongolera chipanduko cha zokutira, ndipo zinthu zinayi zomaliza ndizopanga zitsulo pansi.
1, makina opanga magetsi ndi ma prograung
Makina opanga magetsi ndi mankhwala opangira macheza ndikupanga mapulasitiki apulasitiki ndi njira zopangira makina ndi njira zamagetsi motsatana ndi malo olumikizirana ndi gawo lapansi. Nthawi zambiri amakhulupirira kuti gulu lolumikizana lomwe limatha kukwaniritsidwa ndi makina opangira magetsi ndi pafupifupi 10% yokha ya mankhwala ophulika.
2, degrance
Njira ya Decreatorce ya kukopeka ndi pulasitiki yokhala ndi njira yofanana ndi njira yopangira zokutira.
3, kuzindikira
Kuzindikira ndi kwa Adsorb zina mosavuta oxididzinthu, monga tin dichloride, titanium trichloride, etc., pamtunda wa pulasitiki. Zinthu zomata mosavuta ndi mankhwalawa nthawi yayitali mankhwalawa mankhwala, ndipo oyendetsa amachepetsedwa ku Crystal Crystai ndipo amakhala pamwamba pa malonda. Udindo wa chidwi ndi kuyiyika maziko a mankhwala ophatikizira kupanga chitsulo chosanjikiza.
4, kutsegula
Kuyambitsa ndikuti kuchitira chidwi ndi chidwi ndi yankho la zinthu zachitsulo zogwiritsidwa ntchito. Chifukwa chake ndi kumiza malonda adsorbed ndi woperekera wothandizirana ndi mchere wamtundu wachitsulo chopatsa thanzi, kotero kuti chitsulo chamtengo wapatali, ndipo chimachepetsa chitsulo chamtengo wapatali chimasungidwa Pamaso pazinthu mu mawonekedwe a tinthu tating'onoting'ono, zomwe zimakhala ndi ntchito yamphamvu yothandizira. Pamene ili ili kumizidwa mu njira yolemba mankhwala, tinthu timeneti tinthu tating'onoting'ono timakhala malo oyandikana nawo, omwe amathandizira kuti zochita za mankhwala.
5, kuchepetsa mankhwala
Musanayambe kupanga mankhwala, zinthu zomwe zidayambitsidwa ndikutsukidwa ndi madzi oyera zimamizidwa mu ndende inayake yopezera yankho la mankhwala ogulitsa mankhwala kuti muchepetse. Izi zimatchedwa chithandizo chotsitsa. Pamene mkuwa wa zamakamwa umayikidwa, formaldehyde amagwiritsidwa ntchito pochepetsa chithandizo, ndipo mankhwala a mankhwala akapatsidwa mankhwala, sodium hypophosphite amagwiritsidwa ntchito pochepetsa chithandizo.
6, kuphika kwamankhwala
Cholinga cha kugwiritsa ntchito mankhwala ndikupanga kanema wachitsulo pamwamba pa pulasitiki kuti apange malo a electrofrating zitsulo. Chifukwa chake, kuphika kwamankhwala ndi gawo lofunikira mu mabala a pulasitiki.
