Malinga ndi ziwerengero zosakwanira, kuyambira ku Ogasiti 16, kuwonjezeka kwa mankhwala osokoneza bongo omwe makampani ogulitsa adapitiliranso, ndipo msika wonse wayambiranso. Komabe, poyerekeza ndi nthawi yomweyo mu 2022, idakali pansi. Pakadali pano, kusintha komwe kumabwezeretsanso m'mafakitale osiyanasiyana ku China sikwabwino, ndipo ndikadali aulesi. Pakukhala kusintha kwachuma, kubwezeretsanso mu mitengo yaiwisi ndi machitidwe osakhalitsa omwe amapangitsa kuti zikhale zovuta kukwera kwa mitengo.
Malinga ndi kusintha kwa msika, talemba mndandanda wa mtengo wopitilira 70, motere:

Epoxy ule:Chifukwa cha kukopa kwa msika, makasitomala ocheperako a madzi a epoxy ku South China ali osamala ndipo alibe chidaliro pamsika wamtsogolo. Msika wamadzimadzi wa epoxy ku Epoxy ku China ku East China ndi osasunthika komanso pamlingo wapamwamba. Kuchokera pamsika, ogwiritsa ntchito pansi pano sagula biluyo, koma agwirizane, ndipo chidwi chawo chimakhala chotsika kwambiri.
Bisphenol a:Poyerekeza ndi zaka zam'mbuyomu, mtengo wamsika wazolowera ku Bisphenol A akadali pamlingo wotsika, ndipo padakali malo ambiri kuti apititse patsogolo. Poyerekeza ndi nthawi yomweyi chaka chatha ku 12000 Yuan / Toni, yatsika pafupifupi 20%.
Titanium Dioxide:Ogasiti akadali nyengo yotsika kumapeto, ndipo mabizinesi ambiri omwe adakwapulidwa a Rigid akufunafunafuna ndalama zomwe mwezi watha. Pakadali pano, kufunitsitsa kugula zochuluka zafooketsa, kumabweretsa volima yamasika yotsika. Pamalo opanga, opanga omwe amapangira amagwirabe ntchito yokonza kuti achepetse kupanga kapena kusintha mindandanda nthawi yanyengo, zomwe zimapangitsa kuti zikhale zotsika pamtunda. Posachedwa, pakhala kusintha kwamphamvu kwa mitengo ya Titanium ya Titanium ya Titide, yomwe yathandiziranso momwe ziliri m'mwamba za mitengo ya Titanium Dioxide. Poganizira zamisika ingapo, msika wa Titaniachi wa Titania ndi pano pakalipano.
Epoxy chloropropane:Mabizinesi ambiri opanga amakhala ndi madongosolo atsopano, pomwe zigawo zina zimakhala ndi malonda osayenera komanso otumiza. Madongosolo atsopano amatha kukambirana, pomwe mabizinesi akugwa amakhala osamala potsatira. Ogwiritsa ntchito ambiri amadera nkhawa za kusintha kwa ntchito yamakono.
Propylene:Mtengo waukulu waukulu wa Shandong ku Shandong amakhala pakati pa 6800-6800 Yuan / Toni. Zikuyembekezeredwa kuti kupezeka komwe kumachepa, kotero makampani opanga achepetsa mitengo yawo yolembedwa, ndipo msika wa msika umayang'anabe kuti usasunthire m'mwamba. Komabe, kufunikira kwa polypropylene sikunafookebe, komwe kwasokoneza ena pamsika. Kugwira ntchito kwa mafakitale ndi kochepa, ndipo ngakhale mitengo ndiyokwera, kuvomerezedwa kumakhalabe. Chifukwa chake, kuwonjezeka kwa msika wa Propylene kuli kochepa pamlingo wina.
Phthalic tentydride:Mtengo wa Riw Starto Tortho Benzene akupitilizabe kukhala okwera, ndipo msika wa naphthalene umakhazikika. Pali chilimbikitso chotsika mtengo, ndipo chifukwa cha mtengo wotsika mtengo, kutsika kwambiri machitidwe ochulukirapo pang'onopang'ono, kumasulira voliyumu ina, kupangitsa kuti pakhale kutulutsa fakitale mpaka pafakitale.
Dichloromethane:Mtengo wonse wakhala wolimba, ngakhale mitengo ina idakulira pang'ono, kuwonjezeka ndikochepa. Komabe, chifukwa cha malingaliro amsika omwe amakhudzidwa ndi Beark, ngakhale zizindikiro zolimbikitsira zolimbikitsa, mlengalenga umakhudzidwa ndi Beat. Kusonkhetsa kwa malonda pano ku Shandoong kuli kokwera, ndipo banklog ya mabizinesi akuthamanga. Zikuyembekezeredwa kuti pakhoza kukhala kukakamizidwa kwina kwa theka sabata yamawa. Ku Guangzhou ndi madera ozungulira, kufufuza kumakhala kochepa kwambiri, kotero kusintha kwa mitengo kunganenedwe pang'ono kumbuyo kwa Shandong.
N-waninol:Kutsatira kuchuluka kwa ma metanol, chifukwa chiyembekezero chothandizira kukonza pa chipangizo, ogula pansi pano amawonetsanso kugula kwabwino panthawi yokonza mitengo, motero n-aninol akuyembekezeka kukhala ndi ntchito yochepa nthawi yochepa.
Acrylic acid ndi ester:Zolimbikitsidwa ndikuwonjezereka pakuwonjezereka pamtengo wa riw matope a nthito ndi malo osakwanira a elster, omwe adalimbikitsa kufunikira kokhazikika kuchokera pansi, ndipo malo ogulitsira asunthira m'mwamba . Zikuyembekezeredwa kuti ma bustfortive attiction andlel apitilizabe kuchita zinthu mwamphamvu, ndipo msika wa elester ukuyembekezeka kupitiriza njira yake yonse. Komabe, chidwi chimayenera kulipidwa kutsika kotsika kwambiri kwa mitengo yatsopano.
