Chopangira utoto cha polymer chokhala ndi magwiridwe antchito apamwamba komanso kulemera kwa 'ma molekyulu' | Malangizo abwino kwambiri a chisankho cha malonda
kulemera kwa maselo a polima
Mu mankhwala a chikopa, funso limodzi lofunika kwambiri pankhani ya zinthu zopangidwa ndi polima ndilakuti, nthawi yomwe chinthucho chili ndi mamolekyulu ang'onoang'ono kapena macro.
Chifukwa pakati pa zinthu zopangidwa ndi polima, kulemera kwa mamolekyulu (kunena zoona, kulemera kwa mamolekyulu apakati. chinthu cha polima chimakhala ndi zinthu zazing'ono komanso zazikulu, motero polankhula za kulemera kwa mamolekyulu, nthawi zambiri chimatanthauza kulemera kwa mamolekyulu apakati.) ndi chimodzi mwa zinthu zofunika kwambiri zomwe chinthucho chimafunikira, chingakhudze kudzaza kwa chinthucho, kulowa kwake komanso chogwirira chofewa komanso cholimba cha chikopa chomwe chingapereke.Zachidziwikire, katundu womaliza wa chinthu cha polima umagwirizana ndi zinthu zosiyanasiyana monga polymerization, kutalika kwa unyolo, kapangidwe ka mankhwala, magwiridwe antchito, magulu okonda madzi, ndi zina zotero. Kulemera kwa mamolekyu sikungaganizidwe ngati chizindikiro chokha cha katundu wa chinthucho.
Kulemera kwa mamolekyu a zinthu zambiri zosungira ma polima pamsika ndi pafupifupi 20000 mpaka 100000 g/mol, ndipo katundu wa zinthu zomwe zili ndi kulemera kwa mamolekyu mkati mwa nthawiyi zimasonyeza kuti zili ndi katundu wofanana.Komabe, kulemera kwa mamolekyu a zinthu ziwiri za Decision kuli kunja kwa nthawiyi mosiyana.

Kuthamanga kwabwino kwambiri kwa kuwala | Malangizo abwino kwambiri a chisankho cha mankhwala a syntan
Nthawi zonse pamakhala zinthu zakale zomwe timapeza m'moyo wathu zomwe zimatipangitsa kumwetulira nthawi iliyonse tikaganizira za izo. Monga nsapato zoyera zachikopa zomwe zili mu kabati yanu ya nsapato.
Komabe, nthawi zina zimakuvutitsani kukumbukira kuti pakapita nthawi, nsapato zomwe mumakonda sizidzakhalanso zoyera komanso zonyezimira, ndipo pang'onopang'ono zimakhala zakale komanso zachikasu.
Tsopano tiyeni tidziwe chomwe chili kumbuyo kwa chikopa choyera——Mu 1911 AD Dr. Stiasny adapanga tannin yatsopano yopangidwa yomwe ingalowe m'malo mwa tannin ya masamba. Poyerekeza ndi tannin ya masamba, tannin yopangidwa ndi yophweka kupanga, ili ndi mphamvu yabwino yopaka utoto, mtundu wopepuka komanso yolowera bwino. Chifukwa chake yakhala yofunika kwambiri mumakampani opanga utoto pazaka zana zapitazi. Muukadaulo wamakono wopaka utoto, mtundu uwu wa tannin yopangidwa umagwiritsidwa ntchito pafupifupi pazinthu zonse.
Chifukwa cha kapangidwe kake kosiyana ndi kagwiritsidwe ntchito kake, nthawi zambiri amatchedwa tannin yopangidwa, tannin ya phenolic, tannin ya sulfonic, tannin yofalikira, ndi zina zotero. Chofala cha ma tannin awa ndichakuti monomer yawo nthawi zambiri imakhala ndi kapangidwe ka mankhwala a phenolic.

Kapangidwe kabwino kwambiri koyeretsa khungu, kusunga chogwirira chomasuka｜ Malangizo a chisankho cha DESOPON SK70 ndi chinthu chabwino kwambiri.
Kodi thovu ndi chiyani?
Ndi matsenga oyandama pamwamba pa utawaleza;
Ndi kuwala kokongola pa tsitsi la wokondedwa wathu;
Ndi njira zomwe zimasiyidwa pamene dolphin imadzimira m'nyanja yabuluu yakuya ...Kwa opaka utoto, thovu limayamba chifukwa cha mankhwala amakina (mkati mwa ng'oma kapena ndi mapadi), omwe amaphimba mpweya mkati mwa zigawo za surfactant za madzi ogwira ntchito ndikupanga chisakanizo cha mpweya ndi madzi.
Thovu silingapeweke panthawi yonyowa. Izi zili choncho chifukwa, panthawi yonyowa, makamaka nthawi yobwezeretsa utoto, madzi, zinthu zosungunulira ndi mankhwala amakina ndi zinthu zitatu zazikulu zomwe zimayambitsa thovu, komabe zinthu zitatuzi zimakhalapo pafupifupi nthawi yonseyi.Pakati pa zinthu zitatuzi, surfactant ndi chimodzi mwa zinthu zofunika kwambiri zomwe zimagwiritsidwa ntchito popaka utoto. Kunyowetsa kofanana komanso kokhazikika kwa kutumphuka ndi kulowa kwa mankhwala mu kutumphuka zonse zimadalira izi. Komabe, kuchuluka kwa surfactant kungayambitse mavuto a thovu. Thovu lochuluka lingayambitse mavuto pakupita patsogolo kwa njira yopaka utoto. Mwachitsanzo, zingakhudze kulowa kofanana, kuyamwa, ndi kukhazikika kwa mankhwala.

DESOATEN ARA Amphoteric Polymeric Tanning Agent ndi DESOATEN ARS Amphoteric Synthetic Tanning Agent | Malangizo Apamwamba a Chisankho
Pali munthu wotchedwa Wang Yangming mu Ufumu wa Ming. Pamene anali kutali ndi kachisi, anayambitsa sukulu ya maganizo; pamene anali mkulu wa makolo, anathandiza anthu ammudzi; pamene dziko linali pamavuto, anagwiritsa ntchito nzeru zake ndi kulimba mtima kwake kuti athetse kupandukako ndi kuteteza dzikolo kuti lisawonongeke ndi nkhondo yapachiweniweni. "Kukhazikitsa ubwino, ubwino ndi kulankhula si chisankho chachiwiri m'zaka zikwi zisanu zapitazi." Nzeru yaikulu ya Wang Yangming ili m'choonadi chakuti anali wachifundo kwambiri pamaso pa anthu abwino komanso wanzeru kwambiri pamaso pa zigawenga zachinyengo.

Chopangidwa ndi DESOPON USF chofewa kwambiri | Malangizo a Chisankho cha Premium
Kufewa
M'mapiri a ku Ecuador mumamera udzu wotchedwa toquilla, womwe umayambira m'mitengo yake ukhoza kupangidwa ngati zipewa pambuyo pochiritsidwa. Chipewa ichi chinali chodziwika bwino ndi ogwira ntchito ku Panama Canal chifukwa chinali chopepuka, chofewa komanso chopumira, ndipo chinkadziwika kuti "chipewa cha Panama". Mutha kuchipinda chonsecho, kuchiyika mu mphete ndikuchitsegula popanda makwinya. Chifukwa chake nthawi zambiri chimayikidwa mu silinda ndikukulungidwa pamene sichinavalidwe, zomwe zimapangitsa kuti chikhale chosavuta kunyamula.
Chimodzi mwa ziboliboli zodziwika bwino za Bernini ndi "Pluto Snatching Persephone", komwe Bernini adapanga chomwe mwina ndi marble "wofewa kwambiri" m'mbiri ya anthu, kuwonetsa kukongola kwakukulu kwa marble mu "kufewa" kwake.
Kufewa ndi lingaliro loyambira lomwe limapatsa anthu chidziwitso cha umunthu wawo. Anthu amakonda kufewa, mwina chifukwa sikutibweretsera mavuto kapena chiopsezo, koma chitetezo ndi chitonthozo chokha. Ngati masofa onse m'nyumba za ku America anali okongola ngati a ku China, sikuyenera kukhala ndi sofa zambiri, eti?
Chifukwa chake, pa chikopa, kufewa kwakhala chimodzi mwa zinthu zomwe ogula amazidziwa kwambiri. Kaya ndi zovala, mipando, kapena mpando wa galimoto.
Chinthu chothandiza kwambiri popanga chikopa ndi fatliquor.
Kufewa kwa chikopa ndi zotsatira zake osati cholinga cha fatliquor, chomwe ndi kuletsa kapangidwe ka ulusi kuti kasamamatirenso panthawi youma (kuchepa madzi m'thupi).
Koma mulimonsemo, kugwiritsa ntchito ma fatliquors, makamaka achilengedwe ena, kungapangitse kuti zikopa zikhale zofewa komanso zomasuka. Komabe, palinso mavuto: ma fatliquors ambiri achilengedwe amakhala ndi fungo losasangalatsa kapena chikasu chifukwa cha kuchuluka kwa ma bond osakhuta m'mapangidwe awo. Koma ma fatliquors opangidwa savutika ndi vutoli, koma nthawi zambiri samakhala ofewa komanso omasuka monga momwe amafunikira.Chisankho chili ndi chinthu chimodzi chomwe chimathetsa vutoli ndikukwaniritsa magwiridwe antchito apamwamba:
