Chimachitika M'kati mwa Udzu Kutentha Kukasintha

Mapulasiti apulasitiki achikhalidwe ndi osavuta. Sasamala kwambiri za kutentha kapena kuzizira.Koma udzu wopangidwa ndi manyowa umachokera ku zomera — chimanga, nzimbe, nsungwi, kapena ulusi wa pepala. Zinthu zachilengedwezi zimapangidwa kuti ziwonongeke mutagwiritsa ntchito. Izi ndi zabwino kwa dziko lapansi. Koma zikutanthauzanso kuti zimayankha kutentha ndi chinyezi mukamwa.Udzu wothira manyowa ukakumana ndi kutentha, zinthu zitatu zimatha kuchitika:

• Zinthuzo zimayamwa chinyezi mwachangu
• Kapangidwe kake kamakhala kofewa
• Pamwamba pake pakhoza kutayika kusalala kapena kulimba

Zakumwa zozizira zimachepetsa izi. Zakumwa zotentha zimazifulumizitsa.Ndicho chifukwa chake udzu umodzi sukwanira chikho chilichonse.

Mapepala Opangidwa ndi Mapepala - Oyenera Kumwa Zakumwa Zozizira Mwachangu, Osati Zotentha

Mapepala opukutiraAmapangidwa ndi matabwa okhala ndi utoto wosanyowa. Mu zakumwa zoziziritsa kukhosi (0–7°C / 32–45°F), nthawi zambiri zimakhala kwa mphindi 15–30 pamlingo wabwinobwino wakumwa. Kupatula apo, gawo loviikidwa m'madzi limayamba kufewa pamene madzi akulowa mu ulusi wa pepala.Mu zakumwa zotentha (zoposa 60°C / 140°F), kufewako kumafulumira kwambiri. Kutentha kumawonjezera kuyamwa kwa chinyezi ndipo kumatha kufooketsa zomatira zomwe zimagwiritsidwa ntchito popanga udzu. Pa chakumwa chilichonse choperekedwa chotentha kapena chomwe chikuyembekezeka kudyedwa pang'onopang'ono, udzu wa mapepala si chisankho chodalirika.

Masamba a PLA - Okonzedwa bwino kuti azigwiritsidwa ntchito pa zakumwa zoziziritsa kukhosi

PLA(polylactic acid) ndi bioplastic yopangidwa kuchokera ku chimanga, nzimbe, kapena zomera zina. Masamba a PLA ndi osalala, opirira chinyezi, ndipo amamveka ngati pulasitiki wamba.Mu zakumwa zoziziritsa kukhosi - khofi wozizira, ma smoothies, madzi akumwa, tiyi wothira - udzu wa PLA umagwira ntchito bwino kwambiri. Umakhala wolimba nthawi yonse yomwa, ngakhale utakhudzana ndi madzi kwa nthawi yayitali.Cholepheretsa cha PLA yokhazikika ndi kupirira kutentha kwake. Kutentha kwa galasi - komwe zinthuzo zimayamba kufewa - kuli pafupifupi 55–60°C (130–140°F). Khofi kapena tiyi wotentha wopangidwa kumene nthawi zambiri umapitirira 70°C (158°F), zomwe zimapangitsa kuti udzu wa PLA utayike mkati mwa mphindi zochepa. Zosakaniza zina za PLA zimaphatikizapo PBAT kapena zosintha zina kuti ziwonjezere kupirira kufika pafupifupi 70°C, koma magwiridwe antchito amasiyana malinga ndi wopanga.PLA ndi yabwino kwambiri pa zakumwa zoziziritsa kukhosi. Pa zakumwa zotentha, PLA yokhazikika siilimbikitsidwa pokhapokha ngati yavomerezedwa bwino pa kutentha kwambiri.

Masamba a PHA - Osatentha komanso Odalirika pa Zakumwa Zotentha

PHA (polyhydroxyalkanoate) imapangidwa kudzera mu kuwiritsa kwa bakiteriya kwa mafuta kapena shuga ochokera ku zomera. Ndi mbadwo watsopano wa biopolymer wopangidwa ndi manyowa wokhala ndi mphamvu zosiyanasiyana za kutentha kuchokera ku PLA.Ma PHA straws amapereka mphamvu yolimbana ndi kutentha kwambiri. Kutengera ndi kapangidwe kake, amasunga kapangidwe kake bwino pa kutentha kwa chakumwa chopitirira 70°C (158°F), ndipo mitundu ina imapirira kutentha mpaka 100–120°C (212–248°F) kuti igwiritsidwe ntchito kwa kanthawi kochepa. Mwachidule, ma PHA straws amagwira ntchito bwino mu khofi watsopano komanso tiyi wotentha popanda kufewa msanga.Zogulitsa zake zimakhala zokwera mtengo komanso sizipezeka paliponse poyerekeza ndi PLA. Pa ntchito zomwe zimafuna udzu umodzi wothira manyowa wa zakumwa zozizira komanso zotentha, PHA ndi yabwino kwambiri.

Udzu wa nsungwi ndi ulusi wa zomera - Mphamvu Yonyowa Kwambiri Yochokera ku Zinthu Zachilengedwe

Udzu wa nsungwindi zinaudzu wa ulusi wa zomeraamapangidwa ndi zomangira zochepa kapena zopanda kupanga. Mayeso a makina akusonyeza kuti udzu wochokera ku nsungwi umayamwa madzi ochepa kwambiri kuposa udzu wophimbidwa ndi mapepala pakapita nthawi. Mu mayeso ena oyerekeza, udzu wa nsungwi unayamwa madzi ochepera 60% kuposa pepala patatha maola awiri m'madzi otentha 80°C, pomwe umasunga mphamvu yonyowa kwambiri.Masamba awa amagwira ntchito bwino pa kutentha kosiyanasiyana, kuyambira ma smoothie ozizira mpaka tiyi wotentha. Komabe, kusinthasintha kumasiyana malinga ndi wopanga, ndipo maunyolo ogulitsa sakula bwino ngati a pepala kapena PLA. Ogula ayenera kutsimikizira zomwe zalembedwa mu malonda asanayambe kugwiritsidwa ntchito kwambiri.

Mikhalidwe Yosungiramo Zinthu - Chinthu Chosaiwalika

Maudzu opangidwa kuti asweke atatayidwa, osati panthawi yosungira. Koma kusungidwa kosayenera kungasokoneze magwiridwe antchito a udzuwo usanakhudze chakumwa.Ma udzu a PLA amafunika kusungidwa koyenera nyengo ndi chinyezi chosakwana 50% panthawi yosungiramo zinthu. Kutentha kwambiri kapena chinyezi chokhalitsa kungayambitse kuti PLA iwonongeke msanga kapena iyambe kuwonongeka msanga.Mapepala opukutira ayenera kusungidwa pamalo ouma kutali ndi chinyezi.Ma PHA ndi udzu wa nsungwi nthawi zambiri amakhala okhazikika koma amapindulabe ndi kusungidwa kozizira, kouma, komanso kwamdima.Malangizo othandiza: Sungani udzu wonse wopangidwa ndi manyowa pamalo ozizira komanso ouma, kutali ndi makina otsukira mbale, uvuni, kapena kuwala kwa dzuwa. Gwiritsani ntchito zinthu zakale poyamba.

Zitsimikizo Zomwe Zimatsimikizira Kukhazikika

Si mankhwala onse olembedwa kuti “opangidwa ndi manyowa” omwe amakwaniritsa muyezo wofunikira.kutsimikizira kwa chipani chachitatu, mawuwa ali ndi mphamvu zochepa zalamulo.Malinga ndi FTC Green Guides, kunena kuti chinthu "chingathe kupangidwa ndi manyowa" popanda kufotokoza momwe zinthu zilili kuti chawonongeka kungakhale kosokeretsa. Mayiko angapo, kuphatikizapo Washington ndi Minnesota, tsopano akufuna satifiketi ya chipani chachitatu ngati umboni wovomerezeka wa manyowa.Pa maudzu opangidwa ndi manyowa pamsika waku US, ziphaso ziwiri ndizofunikira kwambiri:

ÜV Austria OK Kompositi KWATHU

Chitsimikizochi chimatsimikizira kuti chinthu chimawonongeka m'malo okhala ndi manyowa - popanda kutentha kwa mafakitale kapena mpweya wowongolera. Ndi muyezo wovuta kukwaniritsa, chifukwa kuwola kuyenera kuchitika kutentha kotsika, kosinthasintha komwe kumakhala kofanana ndi komwe kumayikidwa m'mabokosi a manyowa apakhomo. Zinthu zomwe zili ndi chitsimikizochi zitha kutayidwa m'makina opangira manyowa m'nyumba.

Kukhazikika kwa BPI pa Zamalonda

BPI (Biodegradable Products Institute) imavomereza zinthu zomwe zimakwaniritsa miyezo ya ASTM D6400 ya malo opangira manyowa m'mafakitale. Malo amenewa amasunga kutentha kwa 58 ±2°C (pafupifupi 136°F) ndi chinyezi komanso mpweya wokwanira. BPI yavomereza zinthu zoposa 51,000 zopangira manyowa mpaka pano ndipo ndi satifiketi yodziwika bwino kwambiri yokhudza manyowa ku North America.Zinthu zina zimakhala ndi chimodzi mwa ziphasozi. Zina sizimakhala ndi chilichonse, ngakhale kuti zimagwiritsa ntchito mawu monga "osawonongeka" kapena "ochokera ku zomera." Gulu laling'ono - kuphatikizapo udzu winawake wapadera - limakhala ndi ziphaso zonse ziwiri nthawi imodzi. Ziphaso ziwiri sizipezeka kawirikawiri m'gulu la udzu wopangidwa ndi manyowa, koma zimapereka ubwino wothandiza: chinthu chomwecho chikhoza kupakidwa manyowa m'chidebe chakumbuyo kapena m'mafakitale, kutengera zomangamanga za zinyalala zakomweko.Pofufuza maudzu opangidwa ndi manyowa kuti agwiritsidwe ntchito pamalonda, kufufuza ziphasozi kumapereka chidziwitso chodalirika kwambiri kuposa kuwerenga zomwe zanenedwa pa phukusi lokha.
